oscam clients to oscam server keep disconnecting

= Revision r6234, the problem has existed for a long time yet

= Issue Description I have two dreamboxes in my house, a dm8000 that has a subscribtion card and a dm800 that also uses this card. Both run oscam, the dm8000 as dvbapi client and as cccam+camd server, the dm800 as cccam/camd client (trying both). Both protocols work, but I get excessive disconnects.

= When the issue occurs Completely random.

= How the issue is reproducable Use above setup, zap and wait.

See examples in attached log.

There is NO issue with my network connectivity, both devices are connected to one single switch and I tested connectivity with both ping and ftp, not a single lost packet.
