When clamav-daemon (or all other daemons) remain in sleep mode, I
cannot quickly restart this daemon by /etc/init.d/$(daemon) restart,
I have to wait for a timeout.
Use the kernel sysrq keystrokes to get a task dump to see where
clamav-daemon is sleeping,
I will try tomorrow. I have to build a 2.6.22 (to see if nis works
because it doesn't with 2.6.22-rc7).
Tests made with a 2.6.22.1 (NIS works with 2.6.22.1 and not with
2.6.22-rc7, but I don't know why... ;-) )
my suspicion is that it is stuck
in the kernel futex code somewhere.
I think too.
When I write these lines, my mail server is blocked due to clamd socket
trouble :
Root rayleigh:[/etc/mail] > ps -eLf | grep clamd
clamav 3502 1 3502 1 2 10:53 ? 00:01:23 /usr/sbin/clamd
clamav 3502 1 7226 0 2 12:00 ? 00:00:00 /usr/sbin/clamd
root 8091 5893 8091 0 1 12:18 pts/0 00:00:00 grep clamd
clamd remains in S mode.
I have tried to obtain mode information with sysrq+w without any
success, sysrq+w returns no blocked task. In this example, clamd is
blocked, but some other tasks can be blocked.
