Hi,
I have one master-slave setup.slave pulls index from master after every x
seconds.The problem is for one single replication slot two threads are
getting created and trying to work parallely on same index.this is causing
lock obtain time exception

I am using solr 1.4 and solrj.I am sorry that i mentioned 'x seconds',in fact
its x minutes.
I found the root cause for the problem.I am using EmbededSolrServer to serve
all search requests from my applications.So when the web application starts
one snap puller will be created.And to create EmbededSolrServer i need to
initialize the corecontainer,this initialization is creating one more snap
puller.Thats why it is creating multiple threads.
For time being i solved this issue by replacing EmbededSolrServer with
CommonHttpServer.Everything working fine now.
But is their any other solution that i can use EmbededSolrServer again?

What version of Solr are you using? And it also sounds like you're
polling too often and/or committing too often for good performance.
But the replication is read-only, so I'm surprised you're getting this,
more details please.... Where is the exception occurring?
Best
