aplatypus opened a new issue, #4152:
URL: https://github.com/apache/netbeans/issues/4152
### Apache NetBeans version
Apache NetBeans 13
### What happened
* I have reinstalled Netbeans v13 from the zip file:
* `netbeans-13-bin.zip`
* Started Netbeans and things were running smoothly for about 2 hours.
* At the time I had just finishe an edit and was: `Save All Files` just
before running a debug session.
* The PC went slow
* Finally the `OOM` killer killed Netbeans
```
kernel: [124161.947973]
oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null),cpuset=/,mems_allowed=0,global_oom,task_memcg=/user.slice/user-1000.slice/session-c2.scope,task=java,pid=158987,uid=1000

OOM killer.
rtkit-daemon[1487]: Demoting known real-time threads.

```
* On the command line Netbeans exited with an error exit:
```
$
/prod/tools/netbeans/home/platform/lib/nbexec: line 434: 158987 Killed
"/opt/lib/java/jdk/v17.00/bin/java"
-Djdk.home="/opt/lib/java/jdk/v17.00" -classpath "/prod/tools/netbeans/hom . . .
```
* With a long command line following from the launcher (I guess?)
### How to reproduce
* This has been happening for a while. Previously I was running from a
flatpak Netbeans package
* _see_: #4065
* Now I have unpacked the `netbeans-13-bin.zip` distribution build
* I'm running the command from a bash terminal as follows, to catch any
error messages:
```
nice -n 8 /prod/tools/netbeans/home/bin/netbeans
\
-J-Dawt.useSystemAAFontSettings=on
\
--jdkhome /opt/lib/java/jdk/v17.00
\
--userdir /home/william/.config/netbeans/v13.00/4ams/v17.00/user-02
\
--cachedir /home/william/.cache/netbeans/v13.00/4ams/v17.00/cache-02
&
```
* I am attatching the messages log and a dump file. It seems to blow-up
just before or just after writing a dump file.
* I have a great many ".dump" files. More than I expect in a non-Beta
release that;s for sure
* There is nothing special in the java code for these files.
* To reproduce. Work for a while on a big Gradle project (I have 16GiG ram
is should not be all used like this).
### Did this work correctly in an earlier version?
Apache NetBeans 12.6
### Operating System
Ubuntu 22.04 LTS
### JDK
openjdk version "17.0.1" 2021-10-19 LTS
### Apache NetBeans packaging
Apache NetBeans binary zip
### Anything else
* Lots of .dump files: 378 files
* According to Git, I have only edited 2 files since lunch
* Attaching log and last dump written:
*
[messages.log](https://github.com/apache/netbeans/files/8776535/messages.log)
*
[ProcessNotes_75.dump.log](https://github.com/apache/netbeans/files/8776537/ProcessNotes_75.dump.log)
-- Had to rename it to kee[ github happy.
* I am looking for some way to identify the problem -- I've edited this
project on a desktop with Netbeans (but it has more memory).
