Memory use question

RickNY

Was wondering if someone could take a look at the memory use on my RCC-VE 2440 and let me know if this looks OK.. From what I understand, FreeBSD will load up on inactive memory as cache and consume free memory as needed, and then flush it – is that correct?

last pid: 64534;  load averages:  0.13,  0.39,  0.53    up 2+00:14:42  15:55:55
42 processes:  1 running, 41 sleeping
CPU:  1.4% user,  1.8% nice,  0.4% system,  0.4% interrupt, 96.1% idle
Mem: 960M Active, 2210M Inact, 565M Wired, 416M Buf, 165M Free
Swap: 8192M Total, 90M Used, 8102M Free, 1% Inuse

Thanks,
Rick

Mine looks pretty much flat with little activity around when Snort restarts to load new rules. Do you have package running that uses a lot of memory and does some scheduled stuff?

Edit.
What do you have running package wise on the box although this looks relevant for you as pfsense uses UFS.

This box has two instances of Suricata running, along with Barnyard… I took a look at the logs, and the point where the inactive memory flushes and returns to free memory every other hour and a half or so is when Suricata does automatic cleanup of the logs.

Interesting, do you know if its affecting performance of the system elsewhere?

I dont run Suricata but I wondered if this might be relevant to your situ?

I am not seeing any negative impacts on performance.. Swap usage remains steady at 0%, and the CPU RRD graph looks good, with occasional spikes to 50-60% CPU during rule reloads.. As far as the link you sent – my stats log is being rotated according to the default automatic log cleanup settings under "Log size and retention limits". I have turned off the hard limit on directory size, and my Suricata logs are staying at around 2-3GB with automatic rotation and retention.
