Subject Re: [drlvm][classloader] classloader.StressLoader hangs on my 2-cpu Linux box. Does anyone else see this problem?
Date Thu, 26 Apr 2007 11:06:53 GMT
Naveen,

I observe the same problem on SLES9@x86_64:
classloader.StressLoader, gc.FinAlloc and sometimes
perf.SeveralThreads hang in all 5 exec modes.
After switching to gc_cc this tests start passing. I'm going to create
new JIRA after finishing all tests.
