I recently become an admin of few FreeBSD servers in company in work in for 2 weeks. The guy who set up these isn't working anymore, and i'm only one with some common UNIX knowledge. There is webmin installed, but root account receives mails with following content: From root@modem Wed Oct 20 15:01:04 2010 Date: Wed, 20 Oct 2010 15:01:03 +0200 (CEST) From: root@modem (Cron Daemon) To: root@modem Subject: Cron <root@modem> /usr/local/etc/webmin/bandwidth/rotate.pl X-Cron-Env: <SHELL=/bin/sh> X-Cron-Env: <HOME=/root> X-Cron-Env: <PATH=/usr/bin:/bin> X-Cron-Env: <LOGNAME=root> X-Cron-Env: <USER=root> syslog-ng: not found Out of memory during request for 4084 bytes, total sbrk() is 535412736 bytes! server status: last pid: 1588; load averages: 0.21, 0.22, 0.24 up 92+22:25:16 15:53:56 133 processes: 2 running, 131 sleeping CPU: 1.9% user, 0.0% nice, 16.9% system, 1.1% interrupt, 80.1% idle Mem: 129M Active, 583M Inact, 176M Wired, 41M Cache, 111M Buf, 62M Free Swap: 1473M Total, 32M Used, 1440M Free, 2% Inuse PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 95055 nobody 1 64 0 15908K 8604K CPU0 0 83:48 24.56% smbd 9105 root 1 4 0 7872K 2948K kqread 0 269:08 0.00% cupsd 638 root 1 44 0 3184K 884K select 0 67:00 0.00% syslogd 40008 nobody 1 44 0 41852K 31800K select 1 33:58 0.00% squid 21844 root 1 44 0 8048K 2712K select 0 2:51 0.00% nmbd 429 _pflogd 1 -58 0 3340K 808K bpf 0 2:50 0.00% pflogd 9192 root 1 44 0 15628K 4612K select 0 2:36 0.00% httpd 9141 root 1 44 0 10112K 6016K select 1 2:35 0.00% perl5.8.8 9019 root 1 44 0 3312K 532K select 0 1:34 0.00% proftpd 9274 root 1 44 0 5876K 1032K select 1 1:31 0.00% sendmail Why running out of memory? |

Looks like the script that parses and summarizes the firewall log file is running out of memory, which could happen if your system has a lot of network traffic. If you run /usr/local/etc/webmin/bandwidth/rotate.pl manually and run top at the same time, how much RAM do you see it using at peak?

That's quite probable, because this machine is used for ftp, samba and routing, so __some__ traffic is generated. I will run it manually tomorrow and then check memory usage.

If you don't care about bandwidth stats, you can turn the off completely at Networking -> Bandwidth Monitoring. - Jamie |
