Is there an log option that can let tomcat log the bad query instead just throwing this ?

SEVERE: java.lang.OutOfMemoryError: Requested array size exceeds VM limit

(Tried log level to FULL, but only capture the above)

This is not enough information to further debug
Alternatively, if this can be fixed by allocated more memory by tweaking the following?

-Xms1024M -Xmx4096M -XX:MaxPermSize=256M

Update

-Xms6G -Xmx6G -XX:MaxPermSize=1G -XX:PermSize=512M

(the above seems works better, keep monitoring)

Upgrade solr to a newer version seems have sort this problem, likely newer version has a better heap memory management.
