Looks good. The dev build has been running all morning and I've been running 
builds without any issue. Normally it would manifest pretty quickly.

Well the proposed patch has been merged into the master branch.

Could someone take a chance with the current build?

[https://ci-builds.apache.org/job/Netbeans/job/netbeans-linux/lastSuccessfulBuild/artifact/nbbuild/NetBeans-dev-Netbeans/]

 

Yes, it is a Linux build, but could run on Windows and MacOS as well, just 
download and unzip.

I see _Too many open files_ issue. I'm on:

MacOS Catalina: 10.15.7 (19H114)

openjdk version "11.0.8" 2020-07-14

OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.8+10)

OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.8+10, mixed mode)

 

The projects are Gradle. Netbeans 12.1 works fine with the same projects.

Let me know if you want me to send in logs, etc.

I can confirm the finding by Onno Molenkamp, I'm on a Gradle project as well. 
lsof takes about 40 seconds to even start outputting anything and then it's 
basically every directory in 
{color:#00}.gradle/caches/modules-2/files-2.1/{color}

Memory consumption of NB increases steadily, even if I don't do anything in the 
IDE and just watch (having my Gradle project open). The number of open file 
handles increases at a rate of about 200 per minute. If I then click on "forced 
garbage collection", memory usage is brought back to where I started, but the 
number of open files handles just keeps on increasing. Stopping the IDE brings 
it back down immediately.

There are no stack traces in the log file, the only interesting messages are a 
bunch of those:

{color:#00}Even though the source level of [... some directory in my Grade 
project ...]{color} is set to: 11, java.util.zip.CRC32C cannot be found on the 
system module path:  
Changing source level to 1.8

Scott Palmer commented on NETBEANS-5177:


Interesting. As a temporary workaround, I wonder if users can try to keep 
things under control by manually triggering garbage collection (double click 
the memory histogram on the toolbar), before the problem presents.  Is there 
any finalizer/cleaner that might close the unreferenced Stream?

Most likely the issue is here:

Files.list() shall be called in try with resources, otherwise it won't return 
the directory handles to the OS.

I'm getting the same on both macOS and Linux with Gradle projects.

NetBeans 12.2 is keeping an increasing number of file descriptors to 
~/.gradle/caches/modules-2/files-2.1/*/*/* open (these are directories, not 
files), until it runs out of file descriptors and everything starts to fail.

Matthias Bläsing commented on NETBEANS-5177:


On linux you can use "lsof" to list the open files for a process. Might be 
interesting to compare the lists of Netbeans 12.1 and 12.2 and see if a large 
number of files can be found in 12.2, which are not in 12.1 and fall into the 
same category. It might also be worthy to check if the problem persists when 
running current master, at least the LSP problem is fixed there.

Scott Palmer commented on NETBEANS-5177:


I'm getting these errors after working for a while with Gradle-based projects.  
My guess would be that NetBeans (or the JRE) is leaking file handles.
I'm running NetBeans 12.2 on macOS Big Sur 11.1
{{openjdk version "15.0.1" 2020-10-20
OpenJDK Runtime Environment Zulu15.28+51-CA (build 15.0.1+9)
OpenJDK 64-Bit Server VM Zulu15.28+51-CA (build 15.0.1+9, mixed mode, sharing)
}}

I never noticed anything like this prior to NB 12.2.

Matthias Bläsing commented on NETBEANS-5177:


To me this looks like a misconfigured system (yes maybe even the base 
configuration is broken). I see in the log many entries like:

{{Caused: java.util.zip.ZipException: /Applications/NetBeans/Apache NetBeans 
12.2.app/Contents/Resources/NetBeans/netbeans/platform/modules/org-netbeans-modules-uihandler.jar
 (Too many open files)}}

This varies with files, but when this point is reached, I would not trust the 
system much more. The system assumes, that files can be freely opened and in 
most cases I saw they are jars of the netbeans system, so there is no reason to 
apply limits.

Maybe this helps to track it down? A quick google showed some entries from the 
past where people reported similar problems in the past.

 

One thing that might be interesting (just an idea): What type of projects are 
opened? 12.2 has a bug, that causes an excessive number of subprocesses to be 
spawned when the LSP support (typescript/cpplite projects) is used.

I'm seeing the same thing on macOS BigSur, but it was also happening to me on 
Catalina as well. I never ran into this problem in 12.1 and my current 
workaround is to just use 12.1.

I posted the following in the users mailing list. Hopefully this helps. Please 
let me know if there's other info I could provide that will help debug this.

The windows I saw had messages like :
 
 • Folder org-netbeans-api-project-libraries already exists in 
/Users/blah/Library/Application Support/NetBeans/ 12.2/config
 
 • Cannot get exclusive access to /Users/blah/Library/Application 
Support/NetBeans/12.2/build.properties@bad1856d:5a70225a (probably opened for 
reading)



Here's the thread dump. As I said on the mailing list, my terminal cut off the 
full dump so I only have the tail end of it.

> There is something seriously wrong with 12.2, it is unusable that way.

Please don't overstate. Yes it is bad for you, but in general 12.2 works. Lets 
focus again on the problem. Could you please provide a log from the situation, 
maybe the stacktraces and further information can further narrow it down.

For the deadlock, the log should hold the information, which locks clashed, so 
it might shed some light on this.

Could it be, that the home directory resides on a special filesystem or has 
special handling enabled in the kernel? Deadlocks with directories and files I 
would only expect on windows, where opening a file by default creates a 
mandatory lock, but I'm not aware of similar things on linux, there you can 
even delete an opened file.

Well, unfortunately the IDE crashed again. This time the error messages are 
different, please see screenshot2.png.

I could not even save the changes to an open file, Netbeans would complain that 
it couldn't get exclusive access to it. So I had to kill the IDE and lost all 
unsaved changes.

There is something seriously wrong with 12.2, it is unusable that way.

However, since executing your command I have not experienced any more crashes. 
I do not understand what restorecon does, as I have no experience with SELinux

Try to use the following command:

if that would help then it would be some SELinux issue

I have deleted the file in question and tried again. NB did regenerate the file 
and the crash happened again, this time with a slightly different message, 
which I could not catch, because KDE crashed. But I could read that there was a 
locking contention and "null".

> I experienced a number of total freezes after installing NB 12.2 (have been 
> using 12.0 before), but could not get an error message of any sort, since NB 
> was completely unresponsive to keystrokes or mouse. This changed today, I got 
> an error popup, which I attach. NB was again totally unresponsive, but I 
> could make a screenshot of the popup message.
> The black shadow around the error dialog actually is tens or hundreds of the 
> same popup windows behind the first one. They keep piling up at CPU speed 
> until the app runs out of memory or is killed. For a while I could close a 
> few of them, but they kept coming up faster than I could click.
> The file in question (see screenshot) looks normal to me. It has the correct 
> owner and permissions and its content is this:
> count=1000
> MTTF=71985
> uihandler.preferences.writable.check=1608633016127
> The crash happened directly after starting the IDE, while it was reading in 
> the last project I worked on. No user interaction was involved.
