Hi there, SYS: Debian 3.1, kernel 2.4.27-2-generic alpha GNU/Linux, clamd daemon 0.88.2
When I got in to work this morning my server wiould not allow me (or others) access. Even when I logged into the console and tried to do an `ls` it responded with (35)Resource temporarily unavailable: couldn't create child process: 35 >From what I can find this is either due to lack of memory or some resource >limit. I don't think it's the memory as there is 1.2GB and a huge 36GB swap (long story). procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 0 437744 81976 220776 0 0 23 106 54 48 15 1 84 0 >swapon /dev/sda4 partition 425800 0 -1 /dev/sdh1 partition 35567600 0 -2 I noticed that there are lots of <defunct> clamd processes. If I restart clamd it cleans them up but within 30 minutes I have another 30 defunct clamd processes (yes it does SMTP with clamd enabled). I have tried to comment out the ScanArchive option from clamd.conf. LocalSocket /var/run/clamav/clamd.ctl FixStaleSocket User clamav AllowSupplementaryGroups ScanMail # ScanArchive ArchiveMaxRecursion 5 ArchiveMaxFiles 1000 ArchiveMaxFileSize 30M ArchiveMaxCompressionRatio 250 ReadTimeout 180 ... However I am not convinced that the option is disabled as the log shows "Archive support enabled." So I guess I have a few questions. The server had been up for at least 30 days so I guess the number of defunct processes would have been in the thousands. Does it look like I am looking at the right source of my original resource problem? Apart from getting cron to restart clamd is there something I have overlooked that is allowing the number of defunct processes to grow? Or has anyone had a similar experience that was due to something else? Any ideas would be appreciated. TIA. Dp.
