Openfire+AD delay messages

Hi!

I need your help. We’ve got Openfire server on Windows+AD+embeddedDB+NTLM.

Almost every day at 11-12AM we’ve got same problem. Users send messages to each other but messages deliver with 3-7 minutes delay. And at this moment you can’t login to jabber server with your jabber client.

At this moment debug show this messages

And there are a lot of this messages about every user in our jabber(We have 300+ users). I guess that this is some kind of sync with AD, and it sync all users and groups.

I guess that this sync create a queue of processes and where sync run with higher priority then message delivery.

This problem spoils work.

Hope for your help to resolve this problem. Thanks!
