Subject Re: [jira] Created: (HARMONY-2803) stress.Mix hangs on RHEL4 update 4
Date Wed, 20 Dec 2006 08:52:23 GMT
First of all I would recommend to try this test on RI and see how it
behaves here. This test intensively creates new threads and allocates
memory for a fixed amount of time. So it very probable that it just
consumes all 2GB of the memory on your fast core2 processor for that
time. Another question is why it hangs? It may be a problem of the
test or DRLVM. To understand this first we need to compare it with RI.
If RI works fine then we can try to get the same behaviour on more
slower processors by increasing a time the test operates and
investigate the problem.

Thanks
Evgueni
