RE: [SLE] kernel: VM: killing process

After a little investigation it seems that my system is running out of memory! It looks like a user is trying to allocate more memory that the system has (real+swap). I know that this can be controlled by setting resource limits. But please can someone explain the difference between the following, and where one would use them. datasize stacksize memoryuse vmemoryuse memorylocked I've read the man pages for both bash/ulimit and tcsh/limit but the only limit that seems to make any difference is vmemoryuse. -- Simon Oliver
