Environment

Novell ZENworks 7.2 Linux Management - ZLM7.2

Situation

Mirroring times out when inactive connections reach configured WAN inactive connection time limit and are killed.
Risk for timeouts increase as the number of updates and time to download increases.
All channels are checked even when they are configured for not being needed, which increases time needed for mirroring processes and potential for timeouts.

Resolution

Changing the TCP Keepalive packet configuration / settings (inherent in TCP Protocol) appropriate for the environment (defaults needed to be adjusted) resolved the timeouts.
