System panic due to exim??

Hi,

I'm a bit worried here. Our system panic's due to something that exim
does. Not sure if it's really exim or the system itself, but I've had
2 panic's in the last 5 days and I'm hoping that someone here have seen
something similar or can point me to a solution.

System: SunOS 4.1.3_U1 running Exim 1.61
