Why are you using a thread-pool size of 50? 

Each thread will open a separate thread-local LDAP connection. Also a
pool-size of 50 will put a lot of unnecessary pressure on your database. In
general don't increase the pool size unless you are absolutely sure it is
necessary.

That said, it looks like you found a bug. I'll try to reproduce this.
