Hello,<br>
<br>
i am investigating why our server pairs reboot themselves from time to time.<br>
This is very annoing because these machines are in production and i always<br>
have to fix mysql replications or drbd splitbrains after these reboots.<br>
<br>
We have 3 pairs that use a drbd/xen/heartbeat setup and 2 of these pairs crash,<br>
sometimes every 2 week sometimes only twice a year.<br>
<br>
I first thought it could be heartbeat, but I stopped the service on 1 pair and we also had a crash.<br>
Are there other people who had these kind of crashes?<br>

Yes, sounds familiar... switching to protocol "A" is a workaround that helped for me.<br>
