slow system freeze

[Benjamin Lutz]

Hello,

I'm having a Problem with FreeBSD 5.3 here. The system slowly freezes.

It starts with one application that just locks up. Other applications 
still work, but when I switch to them and do stuff in them, they usually 
lock up after a few seconds as well. Starting new processes or logging in 
at a physical console does not work anymore, and after about 30 secs the 
whole system is frozen. Nothing is printed to the first physical console 
or the logs. This has happened both under load and while the system was 
mostly idle (just me irc'ing).

Now, I realize that this description is very vague, but maybe you can tell 
me how to even start debugging this? There's no panic, ie no kernel dump 
I could analyze.

I'm no kernel developer, but if I had to guess it sounds like a scheduler 
problem, ie some table being overwritten.

I've attached my dmesg for reference.

Greetings
Benjamin
