Not sure its relavent but these numbers are off;

dbc_max_pct 0 - 0
dbc_min_pct 0 - 0

I'd set max to 7 and min to 5.

Don't have a wide range, its costly in cpu terms for a system to change thsi figure. But zero, that seems wrong.

I have all the systems set like this, so thats not concern for me..We have big database systems, terabytes is being handled, so CPU is a big concern...
Thanks

Looks to me like you need to increase maxssize (if it's a 32 bit app you're failing on). I've got a hard time believing that you're running out of stack if it's a 64bit app with the setting I'm seeing... however, if that's it, you can try that too(maxxsiz_64bit). Also, check out your ulimits... (ulimit -a).
