java.net.SocketException (operation in progress) while using JNDI LDAP pool
Hi all.
We've been using the integrated JNDI LDAP connection pooling capability for a few months now, and I just started seeing these exceptions in our test environment. Does anyone know of a way to avoid them? They are transient and will go away on their own (indicating slow connection startup maybe?)

As far as we can tell, there are no errors in the LDAP server itself.Connections do get closed and returned to the pool every time they are used.
