Comment 1 Jesse Glick 2011-01-19 14:58:08 UTC

OpenProjectList.printMsg apparently was appending to a StringBuffer already at 35M chars. I guess this logging is not really so important that it can't be suppressed at some cutoff?

Comment 2 Jaroslav Tulach 2011-01-21 03:29:56 UTC

I guess we can remove the logging completely, as the problem is fixed for few years already.

Comment 3 Jesse Glick 2011-01-21 13:48:19 UTC

That's one option. I was thinking to just truncate anything over some modest length limit. (I don't know why the output was so voluminous in this particular case - many open projects? Some weird long label in one project? Heap dump might hold a clue but I did not spend too long looking at it.)

BTW gunzip on the dump.gz gives me an EOF error but gzip -d -c dump.gz > dump seems to produce a usable result.

Comment 4 Jan Lahoda 2011-01-21 18:18:26 UTC

FWIW, I have a heap dump where this char[] takes ~196MB - was trying to start IDE with ~1000 project opened.
