Subject Re: java.lang.OutOfMemoryError: PermGen space when reopening solr server
Date Thu, 02 Sep 2010 07:04:06 GMT
Hi,

that issue is not really related to solr. See this:
http://stackoverflow.com/questions/88235/how-to-deal-with-java-lang-outofmemoryerror-permgen-space-error

Increasing maxpermsize -XX:MaxPermSize=128m does not really solve this
issue but you will see less errros :-)

I have written a mini monitor app which I am executing before reloading
to make sure I have enough permgensize.
But you can see the current permgensize usage easily e.g. with jvisualvm.

Regards,
Peter.
