i can take a look at your database... but generally... look at your LOG_DB ... disable all the logs

another thing you can do is lowering monster count [do the first thing, and see if it will work with you]
but yeah, generally i need to take a look at what is using most of the shardmanager resources... to tell you how to reduce it, but seriously, upgrading hardware works really well.
you might also just have data loss going from server 1 -> server 2 or backwards, if that happens and the relay time is too long, the shard will crash, which happens i guess to you.
so yeah... lots of things to verify, its probably not just 1 problem.
