 |
|
Hi,
I have a server running amavis and clamd etc. Over the past 3 weeks my memory footprint for clamd has been huge!
| Code: | top - 14:03:00 up 3:48, 1 user, load average: 1.78, 1.76, 1.58
Tasks: 108 total, 1 running, 107 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.6%us, 0.4%sy, 0.0%ni, 79.1%id, 19.8%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 553176k total, 546528k used, 6648k free, 916k buffers
Swap: 262136k total, 176160k used, 85976k free, 165516k cached
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
4232 amavis 21 3 311m 223m 624 S 0 41.3 0:15.60 clamd
4241 amavis 34 19 3316 852 796 S 0 0.2 0:00.02 freshclam
4300 amavis 15 0 76068 2096 1632 S 0 0.4 0:01.75 amavisd
6126 amavis 16 0 78792 44m 2912 S 0 8.3 0:01.81 amavisd
7111 amavis 15 0 77208 42m 2912 S 0 7.9 0:00.72 amavisd |
This results in my system swapping memory all the time and its driving me crazy!
Until before Christmas I used to run quite happily without swapping etc.
Does anyone have any ideas?
Rich. |

So what changed? Something must have if it didn't used to do this.
However, I've always found it to be a memory hog. A quick restart of the process brings a significant drop. |

I'm having the same issue:
| Code: | PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
3636 clamav 18 3 407m 266m 1096 S 0 26.1 4:24.20 clamd |
I don't suppose you ever found a fix?

I think it was because I was using external signature db's from msrbl.com that looked eating up memory each time they updated at night.
Recently tho, things have been ok. i'm not sure if the upgrade to clamav-0.95.1 fixed it or something else? |

Hmm... I'm just using the default signatures provided by freshclam, so I that shouldn't be the problem here. I'm also still using version 0.94.2, which is the latest stable version. I had seen that that 0.95.1 was available, but I'm trying to stick with "stable" packages on this server. Guess I'll need to try upgrading, though. I restarted clamd shortly after posting my previous message, and it jumped to nearly 200 MB almost instantly. Now, it's back up to 330 MB again.
Thanks for the feedback. I'll try updating and post back the results.

Don't forget that the 0.95 packages are stable from ClamAV, its just in the Gentoo world they aren't.
I've always used the unstable Gentoo ClamAV package and never had an issue. |
