File Transfer Issue

Hi

We’ve been using Openfire-Spark during a week and all worked like a charm. But now we have a strange issue. For some reason, when we do a file transfer, the receiver get’s a 2% process bar freeze but gets the file. The sender status appears as 100% done. It’s not a big deal but it’s annoying because the receiver must check if the file is already transferred. This is only happening with two users, all the other work fine.

I’m using OpenFire 3.7.1 under CentOS 6.3 Server. Users attached thru Active Directory. Clients have last Spark versions of Windows and Mac. Operatings systems Windows 7 Pro and Ultimate, and OSX 10.7.4 lion.

Someone has any idea of this?

Many thanks.

Felix
