Steve, There are some locks involved in search, like the one that gets written to the FS before the readers reads all the segment/index files listed in segments file. Once they are all read, the lock is released. Setting lock dir to the local /tmp doesn't sound good, as locks have to be in the common location in order for them to have the desired locking effect.
As for suggestion for large frequently updated indices - have you considered NAS?

We have a cluster of 2 servers that execute searches and one server in the back end that writes to the index. I thought that setting up the external boxes on nfs would be alright since searching doesn't require locking. Can anyone tell me why this may be happening and possibly suggest a fix for the solution? I've already tried setting -Dorg.apache.lucene.lockDir=/tmp in the JVM args but it doesn't seem to do the job. I have also considdered local filesystems on each cluster member but the index is updated frequently and would need to be mirrored too often for it to be worth while. Any suggestions would be helpful. Thank you, Steve.
