: > 5) are these errors appearing after Solr crashes and you restart it? : : : Yep, I can't find the logs but it's something like can't obtain lock for : <somefile>.lck Need to delete that fiile in order to start the solr properly
wait ... either you missunderstood my question, or you just explained what's happening. If you are using SimpleFSLock, and solr crashes (OOM, kill -9, yank the power cord) then it's possible the lock file will get left arround, in which case this is the expected behavior. there's a config option you can set to tell solr that on start up you want it to cleanup any old lock files, but if you switch to the "single" lock manager mode your life gets a lot easier anyway. But you never mentioned anything about the server crashing in your original message, so i'm wondering if you really ment to answer "yep" when i asked "are these errors appearing *after* Solr crashes" -Hoss
