Hi guys
I'm facing an error in our production environment with our search
application based on maven with spring + solrj.
When I try to change a class, or try to redeploy/restart an application,
I catch a java.lang.OutOfMemoryError: PermGen
I've tryed to understand the cause of this and also I've succeded in
reproducing this issue on my local develop environment by just
restarting the jetty several time (I'm using eclipse + maven plugin).
The logs obtained are those:
[...]

The exception is always thrown while solr init is performed after a
restart (this is the reason why I'm asking your support ;) )
It seems that while solr is trying to be set up (by [Timer-1]), another
thread ([Finalizer]) is trying to close it. I can see from the Solr code
that this exception is thrown always in the same place: SolrCore.java:1068.
Here there is a comment that say:
// need to close the searcher here??? we shouldn't have to.
throw new RuntimeException(th);
} finally {
if (newestSearcher != null) {
newestSearcher.decref();
}
}
I'm using slorj lib in a Spring container, so I'm supposing that Spring
will manage the relase of all the singleton classes. Should I do
something other like force closing solr?
Thanks in advance for your support.
Best regards
Antonio
