Has anyone deployed Media Server 2 on this version of Linux -RHE 4.0 ?

It's certainly supported, the printed documentation backs this up.

The problem appears after time, when the fms service seems to hibernate and
stops all streamed (RTMP) content from working.

The server works for days, then without warning stops. Only restarting the
fms service fixes the problem (have implemented a cron job to restart daily as
a dirty workaround - not ideal)

All ideas / help much appreciated.

Thanks

Dan
