Subject [jira] Commented: (DERBY-956) OutOfMemoryError: Java heap space in stress.multi
Date Wed, 22 Feb 2006 20:34:43 GMT
    [ http://issues.apache.org/jira/browse/DERBY-956?page=comments#action_12367402 ] 

Rajesh Kartha commented on DERBY-956:
-------------------------------------

I am starting to think if this failure is caused due to some kernel issue.  I used one of
the recent builds 10.2.0.0 alpha - (379197) to investigate this failure.

But any number of runs on:

   - Linux  2.6.5-7.244-smp #1 SMP Mon Dec 12 18:32:25 UTC 2005 i686 i686 i386 GNU/Linux
    (with JVMs ibm142, ibm15, jdk142  and jdk15 (build 1.5.0_06-b05) )

   - SunOS 5.10 Generic_118822-25 sun4u sparc SUNW,Ultra-4 Solaris and jdk 15 (build 1.5.0_06-b05)

did not yield the OutofMemory exception for this test.

On the contrary,  with the following Linux:

Linux 2.4.21-27.ELsmp #1 SMP Wed Dec 1 21:59:02 EST 2004 i686 i686 i386 GNU/Linux
(This seems to be the same version,  where the failure was initially observed)

for all the same JVMs mentioned above the test fails with OOM  exception each and every time
it is run.

The kernel version in the latter  is  an older one and does seem to be the issue (since the
JVMs used are the same). 

Having said that, if someone else can also confirm the above, we can downgrade this issue
from being a Blocker.
