Subject Re: [jira] [Commented] (BLUR-85) Kill JVM on OutOfMemory Error
Date Sat, 18 May 2013 06:31:42 GMT
I think -XX:OnOutOfMemoryError="kill -9 %p" will automatically detects
the pid. Do we need to pass it explicitly or %p would be sufficient.

Gagan

issue a kill -9 on the process and you can get the pid from the ./pids directory.  Take a
look at the startup/shutdown scripts to get the exact file format.  I think it's "shard-0.pid"
for the first shard process on the computer and "controller-0.pid" for the first controller
and so on for the 2nd and third processes (if any).  Thanks!
