Re^2: Catching processes stuck in an apparent loop

Not using mod_perl, just using Perl v5.8.8
Also using Apache::Session::MySql

So when I view 'top' from SSH I see something like this when I notice a bunch of hangs:

So what I need is for web.cgi and index.cgi to be monitored so that if they run too long they are automatically 'killed'. I know a kill daemon would be the way to go, but I have no idea how to go about it. I've been looking for a few weeks but cannot find anything definative.

thx,
Richard

I think the right question is: why do those processes "hang", which is in fact "don't stop" :) Dodge This!	[reply]

that's exactly what i was trying to point out: first try to fix the problem at the source; rather than working on a cludge/fix before understanding the nature of the problem. many a program work perfectly and only start showing symptoms of a problem when usage ramps up in a production environment. the hardest line to type correctly is: stty erase ^H	[reply]
