There appears to be a memory management bug that affects systems without swap files. Processes are killed off due to the server being "out of swap space" even though top shows some 800MB of "inactive" memory available. Apr 18 18:13:25 pakastelohi kernel: swap_pager_getswapspace: failed Apr 18 21:10:04 pakastelohi kernel: pid 15680 (smtpd), uid 1045, was killed: out of swap space Apr 18 23:14:47 pakastelohi kernel: pid 17730 (smtpd), uid 1045, was killed: out of swap space Configuration: Dual PIII-800, 1GB of RAM swapfile="NO" is set in rc.conf CURRENT from April 18 I suspect that for some reason memory listed as "inactive" by top is not being correctly allocated to new processes when no swapfile is available, since the errors do not appear until memory listed as "free" has dropped to about 1.5-3k. Let me know if you need additional information. --Lucky
