Re: [mat-dev] Eclipse MAT hangs

Hi,

Perhaps it's running out of memory? You could check the log file for anything suspicious (out of memory error), in mat/workspace/.metadata/.log
If that's the case, you can increase the heap (Xmx) in MemoryAnalyzer.ini

You could also check the stack trace at the moment it hangs, see https://wiki.eclipse.org/How_to_report_a_deadlock
I normally use this method https://wiki.eclipse.org/How_to_report_a_deadlock#Using_jps_.2F_jstack_.28requires_JDK_1.6_or_later.29

Hope this helps,
Marc-André

Hi!

There is an issue with Eclipse or MAT, can't figure out exactly what of them is hanging.

It starts to loop in 2 cores of cpu (I have 4 (i5-2310)) and becomes fully unresponsive.

How can I get some additional info from hung state?

Plasma 5. Arch Linux.

Any help would be appreciated.
