Hi all,

I have a difficult to debug problem. It regards mongrel\_rails. I use  
these versions:

Linux kernel 2.6.21-1.3194.fc7  
Mongrel Web Server 1.0.1  
Rails 1.2.3  
mysql-5.0.37-2.fc7

I use mongrel\_cluster with 8 instances. The problem is that from time to  
time some of the instances stop responding.

First I thought it is a problem of rails mysql driver and the mysql  
server. However I installed a locally compiled version and did some  
timeout configurations. So I think that isn’t the problem. Moreover this  
problem sometimes occures immediately after cluster startup.

Please give me any ideas how to fix this problem or any ideas how to  
debug it in more details.

Thank U in advance

Stanislav
