~.~ March 16 Defunct cimservera processes seen on VMware ESX 3.5 running hardware management agentsDetails
Note: This issue is not specific to certain management agents.
This issue was observed to happen on idling VMware ESX hosts with hardware management agents installed and discovered by their corresponding management application. A high number of the defunct processes could result in various symptoms resulting from the VMware ESX service console failing to spawn new processes.
Symptoms include:
If you are able to log in to the service console, you can verify this issue using the following command, which might show from a few up to thousands of cimservera defunct processes:
# ps -ef
root 6232 0.0 0.0 0 0 ? Z Sep24 0:00 [cimservera <defunct>]
root 6377 0.0 0.0 0 0 ? Z Sep24 0:00 [cimservera <defunct>] root 6496 0.0 0.0 0 0 ? Z Sep24 0:00 [cimservera <defunct>] In addition, /var/log/messages shows the failed logins:
Nov 17 18:29:32 blr-cpd-018 cimservera[505]: user "root" failed to authenticate
Nov 17 18:29:34 blr-cpd-018 cimservera[506]: user "root" failed to authenticate Nov 17 18:29:36 blr-cpd-018 cimservera[507]: user "root" failed to authenticate Nov 17 18:29:39 blr-cpd-018 cimservera[508]: user "root" failed to authenticate Solution
If the failed login attempts are the result of misconfigured credentials in the management application, correct this problem first before proceeding to prevent further degradation.
Restart the pegasus process to clear the defunct cimservera processes. Use the following command at the service console:
# service pegasus restart If you are unable to log in to the service console as a result of this problem, there are two alternatives:
Note: This issue is fixed in VMware ESX 3.5, Patch ESX350-200901407-BG: Updates Pegasus (KB 1006657). |
