Symptoms



The following message appears in both the "Errdump" and "RAS" logs:

2016/03/11-16:29:56:564954, [KSWD-1002], 621992/614333, SLOT 7 | FFDC | CHASSIS, WARNING, switchname, Detected termination of process emd:<pid>.

Cause

Brocade defect DEFECT000569678.

This occurs when polling scripts send large amount of "portshow" commands to the "emd" process in a short burst of time.

Example queries seen in "clihistory":

Fri Mar 11 19:55:00 2016         switchname, admin, portshow 8/1
Fri Mar 11 19:55:01 2016         switchname, admin, portshow 8/0
Fri Mar 11 19:55:01 2016         switchname, admin, portshow 8/3
Fri Mar 11 19:55:02 2016         switchname, admin, portshow 8/2
Fri Mar 11 19:55:03 2016         switchname, admin, portshow 8/5
Fri Mar 11 19:55:03 2016         switchname, admin, portshow 8/4
Fri Mar 11 19:55:04 2016         switchname, admin, portshow 8/7
Fri Mar 11 19:55:04 2016         switchname, admin, portshow 8/6

Resolution

Workaround:
Modify the scripts to space out such polling bursts over a larger period of time, use port range in "portshow" commands rather than back to back consecutive polls of individual ports.

Permanent Fix:
Upgrade to Fabric OS 7.4.1b and above.
