Subject cassandra jvm crash in GCTaskThread
Date Wed, 05 May 2010 06:24:39 GMT
Running a cluster of 0.6.1, one of the hosts crashed during GC.
Can anyone suggest what needs tweaking to prevent that?
The last configuration change I made was to
change <DiskAccessMode>standard</DiskAccessMode> (it was auto); but I can't
determine if it's related.

System is 64 bit centos, the rest of the system info is at the bottom of the
email.

The last lines before the crash from system.log are:

And a summary of hs_err is here. The rest is attached. Let me know if you've
see this before and can advice, thanks!
