IndexOutOfBoundsException after disk full on replication
--------------------------------------------------------
Key: SOLR-3023
URL: https://issues.apache.org/jira/browse/SOLR-3023
Project: Solr
Issue Type: Bug
Components: replication (java)
Affects Versions: 3.5
Environment: EC2 instance running Ubuntu 10.04; Solr installed on a
15GB EBS volume
Reporter: Matt DeBoard
I am running Solr 3.5 with a master/slave configuration. Master instance
handles indexing; slave handles queries. I was investigating why changes to
schema.xml were not propogating to production servers (specifically,
implementing index-time synonyms) and saw that my EBS volume was full (15GB).
After freeing some space by deleting an old Solr 3.4 installation that was no
longer being used, I began seeing the following errors from the slave:

This was happening inconsistently. That is, some queries would be handled, some
would not. For instance, the page at http://att-veterans.jobs would NOT render,
but e.g. http://lockheedmartin.jobs would. Restarting the Jetty server did not
alleviate the problem. I diverted all queries to my master instance, which ran
fine with no errors.
Ultimately I solved the issue by deleting the index files and replicating, then
put the slave back into service.
