Hi.
On a dual opteron system with 4 GB of physical RAM and 12 BG of swap
running 5.2.1, I am running a job that produces a seg fault when it
appears to approach the 8GB mark. Limits are reported as follows:
Resource limits (current):
cputime infinity secs
filesize infinity kb
datasize 8388608 kb
stacksize 524288 kb
coredumpsize infinity kb
memoryuse infinity kb
memorylocked infinity kb
maxprocesses 5547
openfiles 11095
sbsize infinity bytes
vmemoryuse infinity kb
and am thinking that it might be the datasize limitation. I have
searched the man and faq as to how to modify datasize to be 12GB (limits
-d 12g) but would like to change this in general. I looked in
/etc/login.conf and see it is unlimited for the default class
(datasize=unlimited).
My question is, how can I change this to avoid this limit in general?
Thanks for your time and efforts. dmesg follows.
