Hi Folksm I'm getting these on a FreeBSD 5.3 box: Aug 19 15:46:32 radius sm-mta[12850]: k7JJk1rt012776: SYSERR(UID0): fill_fd: disconnect: cannot open /dev/null: Too many open files in system Aug 19 15:46:40 radius kernel: kern.maxfiles limit exceeded by uid 0, please see tuning(7). Aug 19 15:46:40 radius kernel: kern.maxfiles limit exceeded by uid 0, please see tuning(7). Aug 19 15:46:35 radius sm-mta[12784]: k7JJk7F0012784: SYSERR(UID0): queueup: cannot create queue file ./qfk7JJk 7F0012784, euid=0, fd=-1, fp=0x0: Too many open files in system I checked, and the system shows: radius# sysctl kern.maxfiles kern.maxfiles: 1416 radius# sysctl kern.maxusers kern.maxusers: 43 I googled and read that kern.maxfiles is dependent upon kern.maxusers and that I shou;d raise maxusers which I tried to do via sysctl: radius# sysctl -w kern.maxusers=50 sysctl: oid 'kern.maxusers' is a read only tunable sysctl: Tunable values are set in /boot/loader.conf My /boot/loader.conf is a zero byte length file. How can I fix this too many open files problem? Thanks, Lisa Casey
