I found locking issues reported against 1.2 and 1.4 on the mailing lists, but
not against 1.3.
We are running five Solr-1.3 shards under OSX on Tomcat under JDK-1.6 without
any problems for quite a while. We copied the instance over to a Linux
environment and now observe occasional deadlocks.
This shard would lock and never recover. Each time a different shard would
would lock.
Any ideas or recommendations?
Regards,
Bernhard
