Andreas, while you are with Linux binary, could you please provide me a
sol-amd64 binary with mallinfo/or whatever logging on Solaris platform?
I can chip in to provide any other necessary information.

Thanks,
Nikhil

Hi Brian,

from your mentioning of

    http://linux-mm.org/OOM_Killer

I conclude you run into this under a Linux distribution. If it is
RHEL4/amd64 
I have a ready-built binary that comes with mallinfo(3) logging and I'm
confident 
this will us help to find the evildoer.

Regards,
Andreas
