Title: OPNsense 21.7.3_3-amd64 High RAM & Swap Usage
Post by: toups on October 19, 2021, 12:05:04 am

I have run into an odd memory issue with the latest version of OPNsense. It has not impacted the performance that I have observed and that might be due to my setup having 16GB of RAM (total overkill i3 box). I have attached a 4 day netdata graphs of the ram and swap so you can observe the abrupt utilization of swap.

I have tried restarting a few services I suspected might be involved; OpenVPN, unbound DNS, squid, maltrailserver, & pf; but no effect on the memory utilization. I haven't able to pinpoint a source of the "memory leak".

Can someone point me in the right direction for tracking down the culprit?

Try to establish the culprit with top.

I don't use a swap partitition, nor a swap file.

I figured it out. It was 'sensor.py' from maltrail. Did a kill -9 and cleaned the up. Memory went back to normal after killing all the stalled processes. Amazing the amount of memory it used.
