Comment:

 Hi Christian,

 Can you rule out swapping?

 It might be worth seeing if strace/truss can shed any light.
 I don't know about Solaris, but Linux's strace has a variety of
 (unfortunately mutually incompatible) timing options:
 {{{
 -c -- count time, calls, and errors for each syscall and report summary
 -r -- print relative timestamp, -t -- absolute timestamp, -tt -- with
 usecs
 -T -- print time spent in each syscall
 }}}

 Alternatively, attaching gdb to a process once it starts misbehaving might
 prove useful.


 Thanks
 Ian
