7531 pegs CPU & becomes unresponsive, even after restart

Has anyone else run into problems with 7531 pegging the CPU & becoming unresponsive? In my case, it happens pretty reliably after I run JUnit tests.

Even worse, after I kill idea & restart it, it comes right back up and pegs the CPU again.

I've figured out that if I patch the iws file to remove the list of file open in idea, that it makes the problem go away (until the next time, that is).

Basically, 7531 is DOA for me.

I've reverted to 7.0.1 and the problem goes away, just FYI.

Just a thought..

Whenever I install a new EAP, I always have to bump up the Xmx in idea.exe.vmoptions file because the setting isn't preserved.

With my main project, IDEA will fail to load and get an OutOfMemory error with whatever the default memory is.

I just downloaded 7531, and I ran it without adjusting Xmx setting, and it came up but it gave me an error message "There's not enough memory to perform the requested operation. Please shutdown IDEA and increase -Xmx setting in C:\Program Files\JetBrains\IntelliJ IDEA 7531\bin\idea.exe.vmoptions"

After changing Xmx setting and restarting it's running fine.

I use the IDEA VM Options plugin just for this reason, and have my max heap size set to 768m.

After pegging the CPU, I left the things running during lunch yesterday. When I returned, IntelliJ had consumed all 768m and was showing the OutOfMemoryError dialog.

I can't even open my project in 7531 where I could just fine in 7523. It hangs here:
 
Perhaps it's the JIRA plugin, I'm not sure, but it's odd it worked in 7523 and not 7531.

Interesting.. so the process was hungw with 100% CPU so I closed it using task manager and tried to re-open IntelliJ to see if it would hang in the same spot and now the project is opening.
 
Something definitely seems funny.

You should try to take cpu snapshot and/or stack trace dump if you can and file a Jira.

Unfortunately, as discussed in http://intellij.net/forums/thread.jspa?messageID=5199441&#5199441, CPU snapshots have been broken (for me, at least) for a while.

Hm...

I have YourKit 6.0.16 installed similar to you, and the cpu and memory snapshot buttons work fine for me in 7531 EAP. This is on Windows XP SP2.

Here is the contents of my idea.exe.vmoptions that I have set in the VMOptions plugin:

-Xms256m
-Xmx1536m
-XX:MaxPermSize=99m
-ea
-agentlib:yjpagent

I was able to use YourKit to grab a CPU snapshot, and attached it to http://www.jetbrains.net/jira/browse/IDEA-16173

It's quite possible its my JIRA plugin - for the IDEA 7 version I'd
switched to using the background process routines, but they seem to be
playing up a bit.

Thou I've not seen the plugin lock up for me here... if you remove it
and that solves the problem let me know (I need to give that plugin some
more loving)
