What does that coorespond to w.r.t. values in ps.
I'm doing : ps -eo sz,rssize,vsize,size
Every 5 minutes (with Munin) and totalling up each of those 4, and
graphing them. None of them appear to be growing. I'm only checking
the db2 processes and totalling up all db2 processes in each of those
I'm reasonably sure it is db2 doing it. If I look at the full
process list with the above, these are the only processes taking any
amount of space, and this is the only thing running on this box.
But so far I think i've determined that "committed" as found in /proc
does not have any equivalent value in the process list. Not that I
have been able to find at least.
I suppose it could be something other than db2 since this is the only
thing I'm graphing in this way. But I'm not sure what else it would
be since I have a number of other equivalent machines and none of them
