Comment 5 Alexander Kouznetsov 2007-11-16 18:19:31 UTC

Reproduced one more time. Tried to invoke take snapshot while Live Results were populating with data. Got the freeze.

Comment 6 Alexander Kouznetsov 2007-11-19 16:49:28 UTC

Reproduced once more. Just started profiling with customized memory settings:
track each 50 object, record stack traces, stack trace limit: 5, disabled Run GC, enabled Threads. IDE became frozen.

Comment 11 J Bachorik 2007-12-11 14:19:52 UTC

fixed in trunk
there was an issue with classloader unloading leading to a deadlock when using live results simultaneously
