Increase the memory for the uml, using 'mem=xxx' on the cmdline. The default is 32m.

Hi Adam,

I let the memory consumtion of "xmlhandler.fcpl" grew with intend to see what will happen.

The result was a kernel panic (which should not happen).

For a reason unknown to me, I was not able the get the backtrace for that panic, do you know how to do ? (see my first mail)

PS: currently I am testing user-mode-linux for a large scale deployment in my company, but Iam faced with a number of unresolved problems. (for sure, most of them due to my lack of understanding how to do it right, but not all). My C coding skills are not good enough to fix the bugs, the only thing I can to is to stress uml and make bugs reproducable, to help the core delopers to fix them.

It looks like you already had it running under gdb. Just put a breakpoint on panic ahead of time, and get a backtrace when you hit it.
