Hello OSF managers
I try to tune my system with the /etc/sysconfigtab
and the ubc-maxpercent parameter :
vm:
ubc-maxpercent = 70
My system :
Alphastation 200 4/166 with 64 Mo of RAM and 384MB of swap
OSF1 V3.2 17
Firmware revision: 3.9
PALcode: OSF version 1.35
The program which takes 70 Mo of memory runs very fast
but sometime the system hang, i have to reset and boot.
The kern.log file says :
Aug 2 16:01:58 come vmunix: UBC write error(4) on device (0, 0) at block 4992 s

I'd like to tune the station for memory pig Fortran programs.
How can i tune my system without crash it ?
Thanks, I'll summarize.
