I am not 100% convinced this is a BM issue but I've got to start
somewhere.... Our SYS volume keeps running out of space and the culprits
are always the .arc files in SYS:\SYSTEM\CSLIB\LOGS\ATLOGS. I have run
CSAUDIT and set logging to archive every day and only keep them for 7 days.
The archives are created but do not ever delete. Is there something
simple that I might be missing?

BM 3.8.4 on NW6.0.5 with surfControl 6. Not using NSure audit.
