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. If I shut down bacula
completely, the memory loads don't go back down
the results from free show that its not being taken up by the buffers
(only about 178mb used by buffers) ,
total used free shared
buffers cached
Mem: 5073956 5056120 17836 0 7528
4877864
-/+ buffers/cache: 170728 4903228
Swap: 2098152 160 2097992
Things aren't getting bad enough to start swapping, however this is
setting off alarms in Nagios as the % of free memory is well below
the warning point, and I've had an unexplained crash or two on this
server. Some memory does seem to free up as its needed (for example
if I open firefox and load up several tabs) but when a job is
running, things always settle back down to around 18mb free.
I am running CentOS 4.1 and the latest version of bacula-fd.
any help would be appreciated,
