Start collecting system stats in regular intervals, like every 60 
seconds, capture memmory stats, process stats, etc.... Then whent he 
crash occurs, start looking at the snapshots leading up to the crash.

(tools use would use are sar, iostat, vmstat, strace, truss) Someone of 
those may be solaris equivalents, I can recall.... btw Dont rely on top 
for gathering performance metrics.
