[Bug 650446] [NEW] Cloud exhausting Permanent Generation space

[Chris Jones]

Public bug reported:

I have a cloud which has been running for a couple of weeks under light-
moderate load and as of last night it has stopped functioning. cloud-
output.log is silent and cloud-debug.log has:

17:53:33 DEBUG [NioServerHandler:Hashed wheel timer #1] Internal Error.
java.lang.OutOfMemoryError: PermGen space

many times over, and eucalyptus-cloud is consuming 100% CPU.

#eucalyptus and some googling indicate that this is java running out of
space in a particular buffer, and that -XX:MaxPermSize=256m would help
avoid/delay this. Also upstream appears to have made such a change for
2.0.

Is this something we should put into Lucid? Are the benefits/dangers
balanced sufficiently? (I have no idea what the drawbacks, if any, are).
