What happens just before the hang?<br>
<br>
If you can reproduce with 2.6.22.19-grsec2.1.11-vs2.2.0.7,<br>
please try to also reproduce with something closer to <a href="http://kernel.org" target="_blank">kernel.org</a>,<br>
just so we can rule out any strange side effects there.<br>
<br>
Good luck.<br>

After this time the Secondary Server was not reachable via Network. <br>
log from secondary node before network crash.<br>
<br>
Feb 8 21:08:52 vserver3-produktiv ntpd[2008]: synchronized to 85.233.96.33, stratum 3<br>
Feb 8 21:17:01 vserver3-produktiv /USR/SBIN/CRON[6004]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly)<br>
<br>
the server was not reachable for 30 minutes after this time pings arrived the machine (nagios) .<br>
<br>
Today i checked the network connection between the hosts. From primary
to secondary pings arrived . Secondary system was very strange . 1 ping
returns afterwards you only could interrupt with Control-C.<br>
<br>
i tried to disable the network interface for drbd witch ifconfig eth1
down . it doesnt seems to work and i interrupted with Control-C.<br>
Only the reboot of the secondary system makes the syncronization and the network working.<br clear="all"><br><br>with kind regards an thx for your help<br><br>Heribert Tockner<br>KT-NET Communications GmbH<br><br><br>
