Environment:
Ubuntu 18.04 (updated)
Eclipse 2020-03
Eclipse installation status is attached.

Recently, my Eclipse started crashing with this error in .metadata/.log file:

A fatal error has been detected by the Java Runtime Environment:

SIGSEGV (0xb) at pc=0x00007f6157671905, pid=4905, tid=11863

JRE version: OpenJDK Runtime Environment (11.0.6+10) (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1)

An error report file with more information is saved as:
/home/ubuntu/hs_err_pid4905.log

If you would like to submit a bug report, please visit:

Core dump is attached.

Most of the times the crash is initiated by “content assist”, e.g. typing and autocomplete activated (both in a typescript or php files).

This is happening way too often, to the extend I am actually not able to work and have to switch temporary to other IDE.

However, I use and love Eclipse (using it last 10+ years), also like CodeMix, so I hope there is some solution.

Hello! I’m sorry you are having issues with CodeMix. I have reviewed your logs and looks like our performance monitor is crashing in this version of eclipse. I have just coded a quick patch to disable this monitoring. Can you please give it a try and see if it works for you?

1. Shut down Eclipse and eclipse/plugins/com.genuitec.eclipse.code.core_3.6.0.202003022006.jar.
2. Download and extract the attached plugins.zip.
3. Paste the content into the eclipse/plugins directory
4. Launch Eclipse and see if it works now.

NOTE: if the file is not located at eclipse/plugins you might find it at ~/.p2/pool/plugins

Cheers!

Thanks Aaron,

I’ve installed it and will test a bit more this weekend.

Note please, the first symptom (before consistent crashing started) was a massive memory hogging, e.g. 32GB memory eaten and then 16GB swap taken when content assist kicked in .. and.. well, you can imagine.

Anyway, let’s see. Thanks again.

[rmmmm]

Does it work with the patch?
I’ve got the same issue and downgraded to 2019-12 because of that.
I’ve already filled the bug at two different places until I ended up here…

[Aaron Lara]

Hello! The patch should no longer be needed, we released an update with a fix for it. Just make sure you have the latest CodeMix installed (2020.4.7)

Cheers!
Aaron Lara
