Server List Bug

After having went through all the gamelogs and having seen no relevant error I have decided to post here.

After about 45 min to an hour of uptime the server just randomly vanishes from the list.

Anyone have a clue or an idea of where I might look since there are no obvious errors.

if i recall right your on a split tier right *2 pcs*
did at anypoint the network drop?
if so try doing a complete system restart. if the server doesnt show in list thats a connection issue not really a server issue.
if that doesnt work try recompressing,sometimes when the network drops if this is the case recompressing helps... its a unix thing i guess its picky.
if its something else let me know
