Good Day all; I'm new here.

We have an urgent problem. A test server which is ready for
demonstration (and purchase from Sun/Oracle) suffers from some kind of
kernel problem: A 32bit process (ksh) started to consume more than 4G
of memory and is still running but defeats some attempts to observe
it:

Memory usage is 4.8G and rising and we're troubled what may cause the
kernel to ignore the 32bit address limit:
prstat 1 | head -3
   PID USERNAME  SIZE   RSS STATE  PRI NICE      TIME  CPU PROCESS/NLWP
  5608 remy2    4930M 4588M cpu9    58    0   0:24:57 5.0% ksh/1
   380 root     8896K 2392K sleep   59    0   0:00:58 0.1% automountd/4

Observing the process is not always possible, some tools fail like this one:
pmap -x 5608
5608:   ksh /home/remy2/prod/test/opensolaris/transactions/daily423 /hom
5608:   ksh /home/remy2/prod/test/opensolaris/transactions/daily423 /hom
5608:   ksh /home/remy2/prod/test/opensolaris/transactions/daily423 /hom
5608:   ksh /home/remy2/prod/test/opensolaris/transactions/daily423 /hom
5608:   ksh /home/remy2/prod/test/opensolaris/transactions/daily423 /hom
5608:   ksh /home/remy2/prod/test/opensolaris/transactions/daily423 /hom
pmap: cannot examine 5608: address space is changing

What should we do in this case? Reboot? How can we prevent this from
happening again during the demonstration on Monday?
