Mongrel users - Dec 2008 - Mongrel_cluster

Hello,

I am having to restart my mongrel_cluster instances every morning because they
are hung.
Has anyone else had this problem.

I am running Red-Hat 5.0 and Mongrel_cluster (1.0.5) and Apache (2.2.3).

I have a strace of the mongrel_cluster when it is hung.

I don''t have mongrels hanging, but I _do_ have mongrels that cease to 
exist without leaving anything in the logs at all. Very odd.
