/var/tmp files system filling up with pdvfs directories

Hello All,

I am looking for some help on what would be the best practice for removing pdvfs directories from the /var/tmp file system?  The /var/tmp file system is filling up with pdvfs directories and I would like to remove these however; the only articale I can find refrerences an EEB fro NBU 7.0.1. 

https://support.symantec.com/en_US/article.TECH153190.html

I don't think this applies becuase currently we are running NBU 7.6.0.2 on all systems in the environment.

Master and Media Servers are running Solaris 10 and NBU 7.6.0.2

All Clients are running NBU 7.6.0.2

Thank you in advance for yoyr help!!
