As far as I could observe, a three day test run of the router/firewall/asterisk box drained around 500 MB of memory: starting at boot time with ~3700 MB, asterisk leaves the box with ~3640 MB after bein started and after three days the system reached ~3150 MB. Stopping asterisk gave back some memory, so ~3300 MB then was for days the final result - not recovering anything further. I use TEMPFS, if it matters, but I checked /tmp and /var/, there were no remnant files so far.

I'll check first to disable some modules in the first place and then try to perform a test with several days of asterisk enabled. _______________________________________________ firstname.lastname@example.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
