It means it can not scan the mail for virus because something is crashing clam antivirus. The quick easy fix is probably a reboot, but something must have killed it.

I have had the same problem, it was due to some memory allocation error. It made mysqld die and then clamd.

to get it working again try:

service mysqld start
service clamd start

it might work for a while and then die again like in my case.  I used a cron entry to start these services every 10 minutes for safety till i had time to reload the server. mine used to die about once a day.

How do i go about writing the cron entry to make it keep starting mysqld and clamd till i can reload?

1. First we create a custom template folder:

mkdir -p /etc/e-smith/templates-custom/etc/crontab

2. Then create a new template file with pico or vi:

vi /etc/e-smith/templates-custom/etc/crontab/78fixclam

3. In the file put the following:

*/10 * * * * root service mysqld start 2>&1
*/10 * * * * root service clamd start 2>&1

4. Then save the file and expand the template:

expand-template /etc/crontab

5. And finally restart cron:

service crond restart

You can view /var/log/cron to see if it works. To undo your changes simly delete the file 78fixclam and repeat steps 4 and 5.

Hope it helps

No, don't do that. In SME7, both mysql and clamd are supervised (by runsv). If they ever die, they will be restarted within 5 seconds.

Thats good to know, my problem was in sme6 so my temporarely fix saved me a lot of time. So if in sme7 runsv restarts mysqld and clamd automatically, why would Scummy then get "Cannot connect to /var/lib/clamav/clamd.sock"?

Maybe his IT person played with it.

Try the following command..

Code: [Select]

[root@tiger ~]# config show clamd
clamd=service
    MemLimit=80000000
    status=enabled
[root@tiger ~]#

and

Code: [Select]

/etc/rc7.d//S80clamd status
