So...way, way back, somewhere around MR4 we started seeing an issue where lots of files (mostly TMP) were being created (and staying) in the xfer_tmp or the xfer folders. For us it was only with SEP, but from what I understand, SAV users were seeing some of this as well.
Symantec wrote a very comprehensive cleanup document (which has since been shortened to reflect the current state of the issue) that detailed how to manually cleanup these files so that they did not return. At that point I did what I normally do...I wrote a script that automated the whole process. For us, even seeing one or two of these a day made my time writing the script worthwhile.
Essentially what the utility does is shutdown the smc service, clean a bunch of directories, restart the smc service and then run an "smc -updateconfig". While I clean the SAV directories as well as the SEP directories (based on the Symantec document above dated 03/22/2010)...I have NEVER tested this on a SAV machine, we are long past that era.
The directories to clean are based on both the "All Users" and "Current User" accounts, because of this, when the utility is launched, I enumerate both local and domain accounts on the machine and then allow you to select which account to run against. If you have a LOT of temp files in a directory, it will take a LONG time to run. As with all my utilities, I would run this FIRST against a NON-production machine, with bogus TMP files, that has been backed up. At least until you're sure it will do what you need.
This utility is really for MR4, RU5 or RU6 or machines that have been UPGRADED to RU6 MP1...if you have a fresh install of RU6 MP1 or later...then the problem should have already been resolved and this utility will do you no good. In fact, directories may have changed in later versions of SEP and you may actually break something. Use your common sense! I make no promises or guarentees. Did you read that last line? Read it again.
Here is what the GUI looks like...pretty straightforward, select an account and then "Squash UM!". Yes, that's a Squash icon in the bottom right corner.
Anyway, enough of the blah, blah, blah. Hopefully this utility will help your situation, I know that it has greatly helped ours.
