Panic in vxdmp:dmp_update_stats is caused when there is a corrupt iostat record.
 

The Call Trace should be similar to Incident  e2183984, sample below:

Workaround:

Disabled vxdmp iostats :    # vxdmpadm iostat stop

Note: For workaround to be persist through reboot the "vxdmpadm iostat stop" statement should be added to the /etc/rc.local file.

Install 5.0MP4HF6 or 5.0MP4RP1 for Linux
