      Hello, I'm having a strange issue where I find that I cannot query the LDAP after a large synchronization operation that occurs at night. The sync deletes and recreates about 25,000 entries with an average of 30 attributes each. Each entry is a separate call to ldapmodify. This condition is 'corrected' by restarting the ldap server. This makes me suspect it is a cache corruption of some sort. I'm not getting anything in the log on the server, this error is client side only. I've tried adjusting cache from 100,000 to 1,000 entries for the partition, as well as enabling and disabling write sync. The JVM is 1 GB xmx.

If so, then please report this to commons-dev@jakarta.apache.org<commons-dev@jakarta.apache.org> as a bug.]
