clamd keeps exiting

[Mipam]

Hi,

I am using clamav to check on virusses.
This works well. However, when i try to use clamd, it never runs long.
Mostly within a minute or a couple, it exists with signal 6.
I am using this libmap.conf

# /etc/libmap.conf
#
# candidate             mapping
#
libc_r.so.5             libthr.so.1     # Everything uses 'libthr'
libc_r.so               libthr.so

[/usr/local/bin/mplayer]                # 'mplayer' uses libc_r.
libc_r.so.5             libc_r.so.5
libc_r.so               libc_r.so

[mplayer]
libc_r.so.5             libc_r.so.5
libc_r.so               libc_r.so

[/usr/local/sbin/httpd]                 # Apache uses libkse
libc_r.so.5             libkse.so.1
libc_r.so               libkse.so

[httpd]
libc_r.so.5             libkse.so.1
libc_r.so               libkse.so

Maybe i should adjust some things to make it work fine?
Did anyone else encouter these problems?
Bye,

Mipam.
