alertd cores sometimes.
This issue causes alertd to restart. At the alertd stopping time, no SNMP traps will be sent.
When a pool associated with a lot of monitors and it goes down, a very long syslog message will be logged. This could cause alertd to core. The syslog messages should be with the following error code. 01070640:5 01070638:5
This issue has no workaround at this time.
An issue that made alertd core on 2 long syslog messages is now fixed.
