Pfsense using swap memory when it shouldn't !?

  • Hi,

    My pfsense machine is up without any restarts for several days, it's working great but i notticed that swap memory using is increasing, yasterday was at 2% now is at 4%…With 40-50% loading of ram, is it normaly ?i thought that swap is used when memory is at full use...

    It depends on the actual usage. If things are really not being used in RAM it can swap out a little to keep using RAM for caching and overall speed. That's really a question for FreeBSD in general though. I thought someone out there had an FAQ/Wiki entry about that for FreeBSD.

  • Not to resurrect a dead(ish) thread but I'm having the same problem.  I assumed it was Snort until I disabled the interface it was listening on.  My swap fills up after a day or so.  The only package installed is snort, but it isn't enabled currently.

    I had dansguardian installed to play with, but that has been removed as well.

  • But… when I removed the snort package outright swap cleared up and system appears to be running normally.

    By the way, the system has 4GB of RAM and is a core 2 duo Intel system.  Shouldn't be a problem, but oh well.  I was planning to bring up snort on a mirror port anyway.
