Symptoms
mcpd can run out of memory and core when a device in a sync group is sending an extremely high volume of sync messages.
Impact
mcpd cores and restarts if it runs out or memory. Only through inspection of the core file can this condition be detected.
Conditions
The exact cause of this is unknown, and it has been seen very rarely with a large sync in a sync group. Large incremental syncs could be a symptom of other things happening between the devices which could trigger the core.
