Oscam Problem

I have been running Oscam for a few weeks now and ever since we have had this setup our viewing stops from time to time for about 10 seconds then comes back to life.
I see this in the log,
10/12/2013 15:46:41 9000160 c e61100 (0963&000000/0000/0F2E/7D:FDFC): found (173 ms) by reader1 (P/2/2/4)

What could be causing this problem as I'm stuck to see why. I see in the log above it's like this user is re-connecting but we don't know why.

Thanks

check your oscam config

add in newcamd keepalive = 1 . in user account to and check
if problem still same try change global settings.

Hi,

These are already added in both sections.

Hi pari,
