Endpoint Protection Small Business Edition

WHY does SEPM 11 create tons of temp folders that never get deleted?

I mean folders like tmpXXXX.tmp that exist in every subfolder of:
C:\Program Files\Common Files\Symantec Shared\SymcData
this folder alone was taking almost 8GB of space on a system drive which space amount was never designed for that when I made this erver 4 years ago (using Symantec SMB 8.0 back then)...

now here i found a real tmp files dump: sesmvirdef64
especially the x64 def (sesmvirdef64) folder which alone was totalling at 6GB !!!! i deleted all those tmp folders from those "sesm" subfolders and now my Win 2003 system drive finally shows 6.5GB free on C: instead of 27MB-700MB free and half of server services (TCPSVCS, SEsclu, DHCP, SEPM database, DNS & file replication, SceSrv policy processing, etc.) failing due to low disk space on a system drive.

We are using the following SEPM version:
11.0.3001.2224

and following clients connect to it:
-Win 2003 Standard SP2 (32-bit) running SEP 11.0.5002.333
-Win 2003 Standard SP2 (32-bit) running SEP 11.0.5002.333
-Win 2003 Standard R2 SP2 (32-bit) running SEP 11.0.5002.333
-win 2000 SP4 running SEP 11.0.5002.333
-win XP x64 SP2 running SEP 11.0.5002.333 x64

any ideas how to solve our problem once and for all and avoid it in future ? thanks!

2 reasons , earlier it was bug because of virus definitions getting corrupted
follow this document and upgrade to MU5 ASAP:)

Symantec Endpoint Protection virus definition folder consumes a large amount of disk space

will do some reading (and upgrading) then, glad to see your replies :)

thanks and take care.

ok, all seems to be working OK, no more problems with low or zero free space on system drive.

I also followed those instructions on wiping symcdata and some other stuff taking space too.

Did you upgrade to RU5?  Apparently, this was a bigger release than MR1 through MR4.  Also, it is my understanding, that RU5 is the first release of SEP11 that fully supports Windows 7 (that would be RU1 for SEBSBE12).
