WMD crashes causing slight interruptions in accelerated traffic.Log messages have the following error
[wmd.ERR]: [util::exception::tag_msg*] = hash:E3EEB4D6A79CBF7B remote_sys:4 remote_hostid:90b11c55c063 age:20526 {sync_recv_update@codec/Cache.cpp:997}
The system generates dumps and snapshots for wmd
Cause
The wmd distributed database is out of sync on one (or more) systems.More often than not the system that crashes is *not* the one with the incorrect database - it is usually the system sending data to itWhile the distributed database remains out sync this crash will happen for every transfer of the data that triggered this
Workaround
Step 1 - stop Wan Memory on all devicesen
conf t
service wm stop
Step 2 - Clear Persistence and WM Cache on all the device
acceleration wm persistence clear
acceleration wm cache clear
Step 3 - Now after doing the above on all the devices, start the process Wan Memory
service wm start
