Subject old searchers not closing after optimize or replication
Date Wed, 20 Apr 2011 06:36:11 GMT
Hello list,

we have the problem that old searchers often are not closing
after optimize (on master) or replication (on slaves) and
therefore have huge index volumes.
Only solution so far is to stop and start solr which cleans
up everything successfully, but this can only be a workaround.

Is the parameter "waitSearcher=false" an option to solve this?

Any hints what to check or to debug?

We use Apache Solr 3.1.0 on Linux.
