Package: none I have random hangups on my system. I can't reproduce them. I can't find the problem. I'm running a debian squeeze Server which is mainly used for kvm-host, apache2, slapd. Please say if you need any further information. uname -a: Linux server 2.6.32-5-amd64 #1 SMP Tue Jun 14 09:42:28 UTC 2011 x86_64 GNU/Linux
dpkg -s libc6 | grep ^Version Version: 2.11.2-10 I often have messages like this in the log before the hangups: BUG: soft lookup - cpu#1 stuck for 61s! smbclient but with different packages. Best Regards and thanks for your Help. Jan Schenck Here comes the log from the last hangup.
