Description Lubos

2003-06-06 02:35:16 EDT

I'm using Version: 2.1.0, Build id: 200303272130.
Sometimes (3-5 times a day) I have to kill my Eclipse cause it takes 100% CPU 
and does nothing.
I'm ready to give further information, just say which.

Comment 1 Philipe Mulet

2003-06-06 04:22:25 EDT

Please provide steps to reproduce. Also start Eclipse with Java console open, 
so that next time it occurs, you press ctrl-pause in console to trigger a 
thread dump which would be informative about what's going on.

You can start Eclipse with console open using -vm .../java.exe (instead of 
javaw.exe).

Also, why did you log this to JDT/Core ? Did you suspect Java tooling to be 
responsible for this ?

Comment 2 Lubos

2003-06-06 05:25:00 EDT

I've put it to Core, cause it seems to me as the nearest possibility.
I'll append the thread traces ASAP

Comment 3 Philipe Mulet

Always the usual suspect <g>

Are all your files local to your machine ? There are known performance issues 
if the disk drive is slow (or using network drives).

Hi,
yes, they are.

Would one of the referenced JAR/ZIP be corrupted ? We are aware of a situation 
where this could cause our indexer to keep retrying to process the corrupted 
JAR over and over again.

No they aren't. The problem occures sometimes, not every times..

Is this still occurring on build 3.0-Milestone-2 ? I suspect this was due to an 
infinite loop in our indexer, which would keep indexing the same JAR over and 
over again... also see bug 39007

As of now 'LATER' and 'REMIND' resolutions are no longer supported.
Please reopen this bug if it is still valid for you.
