WARN [org.ldaptive.AbstractOperation$ReopenOperationExceptionHandler:251] - Operation exception encountered, reopening connection

[Lipscomb, Gary]

Hi list,

New build IdP v4.1

I've just started seeing these errors[1] appear in the idp-process.logs
I have these settings in conf/ldap.properties [2]

The only thing I think may be contributing to this is that I removed
             idp.ldaptive.provider = org.ldaptive.provider.unboundid.UnboundIDProvider
from ldap.properties but from my understanding this is the default setting now

The errors seem to occur in very low activity periods of the IdP.

Regards
Gary
