More on ASSP memory and OpenVZ

My advice to others - beware of running the ASSP beast in a OVZ
container. I suspect the unreliability (due to exceeding memory) while running ASSP in an OpenVZ virtual is due to the way OVZ treats memory requests. If, under OVZ, Java asks for all of memory and then some, it will survive under Linux but not OVZ. OVZ treats the requested poolsize as in use immediately. OVZ doesn't have swap in the virtuals because it uses the swap as extra memory for the virtuals. Running 2.0.1-5.15: The biggest memory hit I see is rebuilding the SpamDB, about 80 Megs (using BerkelyDB). The spamDB is rebuilt within 2 minutes yet the allocation lingers on longer. I've turned off all automatic rebuilding now, to watch for other memory pool leakage. Long run, I'm going to have to migrate to another server or different anti-spam strategy. I really hate spammers. When I think of all antispam work I've had to do because of them over the last ten years.

Why not use a chroot environment?

Alan,
If your looking at virtualization, ASSP on Ubuntu server 9.04 guest OS under VMWare ESXi 4.0 runs fine....

Thanks Paul and Steve and Thomas (who fixed some memory things
recently). I like chroot that's why I used OpenVZ -- it is a super chroot with weird memory management. In this case normal chroot would have been better! If I was starting over Xen and VMware are possibilities. Unfortunately, there's already a ton going on on that server. Luckily, I have a twin server in the same cabinet sitting in hot standby doing nothing else. I'm going to move ASSP when all my tasks marked Urgent, Immediate and "Right Now" are finished -- they keep adding them though.
