Re: [Bacula-users] High memory usage when backing up
Are you on a x86-64 machine? (I'm on Centos 4.1, though updated) If I run anything above 1.38.0, my jobs will eventually run the system out of RAM, and the system won't be able to start more processes: 31-Mar 11:30 duct-dir: bedlam.cse.2006-03-31_04.05.46 Error: open mail pipe /export/bacula/sbin/bsmtp -h localhost -f (Bacula) [EMAIL PROTECTED] -s Bacula: Intervention needed for bedlam.cse.2006-03-31_04.05.46 [EMAIL PROTECTED] failed: ERR=Cannot allocate memory I'd tried all the way up to 1.38.5 I think, with and without -O0, etc, etc. I *think* it specifically started at 1.38.2 or .3, I'd have to check my notes. It's really rather boggling - I'd guess there's a leak someplace.

What you are seeing appears to be normal block device caching under the linux kernel and nothing to worry about.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I've noticed when running 2.6, the machine appears to want to use all of the RAM. However, running more processes will not make it swap until it would have otherwise begun swapping. Seems to handle the memory usage pretty well, IMO. _ _ _ _ ___ _ _ _ |Y#| | | |\/| | \ |\ | | |Ryan Novosielski - User Support Spec.

To explain: buffers = i/o (disk) write buffers cache = i/o (disk) read cache These are dynamic. Linux works on the principle that if the memory isn't being used by software then it can be used for housekeeping. As software demands increase, buffers and cache will decrease. I'm noticing extremely heavy memory loads when running a large bacula job. The system running the fd and director processes spikes to using all but about 18mb of the 5gb of memory installed. If I sort by memory usage in Top, no processes are using anywhere near the missing memory, however the usage only spikes when I run a large backup job ~100 GB) from this machine. That's what I would expect. If I shut down bacula completely, the memory loads don't go back down It won't. See above. free memory in Linux is the amount of ram not being used for i/o buffering or the programs themselves - if you are seeing large amounts of free memory after a few days of operation then you probably have more ram in the machine than it actually needs for the tasks it is performing.
