In addition to the issue described in technote "328959",  VM engineering identified a new file descriptor leak related to the vxesd daemon. This has been addressed in 5.0 MP3 RP4.


vxesd

The Event Source Daemon (ESD aka vxesd) is a Volume Manager (VxVM) component process, first introduced in 4.0 on Solaris. In 5.0 and later, vxesd was included in all Unix/Linux platforms.

vxesd is a 'helper' process that receives notifications of device related events which are used to take appropriate actions. The benefits of vxesd include:

   * SAN Fabric event monitoring & pro-active error detection (SAN event)
   * DMP event logging (DMP event)
   * Automated device discovery (OS event)
   * iSCSI topology discovery


Workaround

Disable the eventsource daemon (vxesd) to prevent the license key from expiring.

# vxddladm stop eventsource


Disable vxesd across a reboot on "Solaris 8 & 9"

To prevent the vxesd daemon from starting on boot-up, comment-out the "vxddladm start eventsource" line from the /etc/rcS.d/S85vxvm-startup2


Disable vxesd across a reboot on "Solaris 10"

To prevent the vxesd damon from starting at boot-time, comment out the if statement surrounding the "vxddladm start eventsource" command in /etc/init.d/vxvm-startup2 file:


## Start Event Source Daemon, to enable dynamic device discovery
##Empty the lock file before starting the daemon
> /etc/vx/.vxesd.lock

if [ -x /usr/sbin/vxddladm ]
then
/usr/sbin/vxddladm start eventsource
fi

Add a "#" to each of the above four lines of the startup script.


Symantec Support Evidence Collection

If the above workaround does not fix the issue, please collect the following content:

# ps -ef | grep vxconfigd
root 60 1 1 Mar 01 ? 4:45 vxconfigd -x syslog -m boot
root 18097 18064 0 12:41:43 pts/1 0:00 grep vxconfigd

In this instance the vxconfigd process id is "60".

# pfiles 60

Optional:

Please run VRTSExplorer and upload the output to our FTP site. The entire updated Veritas toolset, including the latest VRTSExplorer can be download form here:

The fix is also included in Veritas Volume Manager 5.1 RP1.
