Hi, I'm getting memory errors running zope on BSD. I have looked at the archives; applied the relevant patches, but to no avail. My machine has 1 Gbyte of memory. During normal operation, top shows something like this: last pid: 7030; load averages: 0.52, 0.46, 0.35 up 10+13:27:06 06:51:44 5 processes: 1 running, 4 sleeping CPU states: 15.6% user, 0.0% nice, 3.1% system, 15.2% interrupt, 66.1% idle Mem: 193M Active, 545M Inact, 203M Wired, 37M Cache, 111M Buf, 22M Free Swap: 2048M Total, 21M Used, 2027M Free, 1% Inuse PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 6458 zope 2 0 133M 128M poll 3:38 24.16% 24.16% python 6460 zope 28 0 1864K 1008K RUN 0:00 0.00% 0.00% top As you see, there is 22M marked as free and a whopping 545 as Inactive. Now, during normal operation, the 22M will go down until it hits zero and give me memory errors, but the 545M will be still around that number. As I understand it, inactive memory are pages that can be flushed by the OS if needed. Why doesn't this happen? Or is it something else? Douwe Osinga http://douweosinga.com
