WD Preventing shutdown/reboot

CJZ

Basic Pleskian
---------------------------------------------------------------
PRODUCT, VERSION, MICROUPDATE, OPERATING SYSTEM, ARCHITECTURE
Plesk Panel 11.5.30#46
Centos 6.5
AuthenticAMD, AMD Opteron(TM) Processor 6272

PROBLEM DESCRIPTION
Upon a shutdown or reboot, the system shuts down sw-collectd. Further along, it will end wdcollect and the following will occur:
init: psa-wdcollect main process (pid) killed by KILL signal
init: psa-wdcollect main process ended, respawning
wdcollect[pid]: Language en-US is used for sending e-mail messages.
wdcollect[pid]: Failed to connect to database server during the startup. New attempts will be made if needed.
wdcollect[pid]: Server started

I believe this is preventing the un-mounting of drives which in the end freezes the shutdown process on:
Please stand by while rebooting the system...

After this occurs, I have to force the VM off and then boot again.

As far as I know this bug has been completely fixed in Plesk 12.
