Hi Gustaf thanks for the response. I've been looking at this in more detail this afternoon and it does appear to be caused by something in the interaction of our OpenACS application with 4.99.27. As I previously mentioned, it has been running fine on 4.99.24 on the same Ubuntu version. I realise that I may not have been clear on this point on my previous email: this is Naviserver running on Ubuntu in a Docker container. The version of Naviserver is based on this Docker build https://github.com/oupfiz5/naviserver-s6 which I have forked and updated to 4.99.27 (I may well have missed something in updating NS version - maybe I should have waited until oupfiz updates his build).
* I can confirm that nsd-config.tcl runs fine with 4.99.27 * Some good news: I am able to do an OpenACS clean install on Oracle with 4.99.27. I then successfully installed our application using the APM. However, once I restart Naviserver the problems start. * I tried using the openacs-config.tcl that ships with 4.99.27 and the problems are happening with that too. Here is a selection of the kinds of errors I'm seeing: * munmap_chunk(): invalid pointer * free(): invalid next size (fast) * corrupted size vs. prev_size * malloc(): unaligned tcache chunk detected What is odd is that it seems to be able to handle one request before crashing. Eg. I type in the URL, it shows the /register page but then crashes. After restarting, I enter my login details on the register page, press return. It then crashes. After restarting, it successfully logs me, then crashes again. There is no clear pattern in the logs. I thought it might be related to OCSP and disabled that, but the problems continued to occur. Turning on debug hasn't helped - but maybe there is so much information in the log that I have missed something important. What drivers are you referring to in your question? thanks Brian ________________________________ From: Gustaf Neumann <neum...@wu.ac.at> Sent: Thursday 10 August 2023 7:27 pm To: naviserver-devel@lists.sourceforge.net <naviserver-devel@lists.sourceforge.net> Subject: Re: [naviserver-devel] Crashing on all versions >4.99.24 on Ubuntu Hi Brian, The new NaviServer versions are running fine on Ubuntu 22.04. Have you recompiled the drivers you are using with the updated version? A good test for the NaviServer binary is to test it with one of the packaged configuration files, e.g. nsd-config.tcl. all the best -gn On 10.08.23 18:23, Brian Fenton wrote: Hello we have been testing out our OpenACS application on Ubuntu 22.04.2 LTS (previously we only ran on Windows). It was working great with Naviserver 4.99.24 but I have been getting constant crashes on more recent versions. I get this error on 4.99.25, 4.99.26 and today I also got it on 4.99.27. The server runs fine until I click on a page, then it immediately crashes. The log has only the following error: free(): invalid size and today I got this one: [10/Aug/2023:15:02:23][303.7fa3a64ee640][-conn:openacs:default:1:119-] Fatal: received fatal signal 11 We have an Oracle application and are using the latest nsoracle driver, which might be a factor here. We have been running it with a pretty old OpenACS config file, so I am currently looking to merge in all the latest changes to ensure that is not an issue. Also note that I am running Naviserver on Docker on Windows, but as mentioned it was running great on 4.99.24. thanks for any help Brian
