Hi
I’ve been experiencing some random user disconnections since upgrading to openfire 3.4.5
I think some of the exceptions I’m seeing are caused by the already reported problem on LDAP groups (I have this server connected to an AD) but I’m also get different exceptions. Here is an example of warn.log

As I am also getting some of these in debug.log so I’m thinking that maybe is a problem with client compression. What do you think?
