| |
Hi:
I am running kernel 2.1.123 on a couple of workstations and find a reliable way to make the machines completely non-responsive is simply to run a buggy X application which tries to allocate more memory than is availabe. The only way out is a hard reset or a Alt-SysRq sequence. In ordinary circumstances, the memory and swap space on each machine is perfectly adequate and so I don't see "get more memory" as being a solution. I could just get rid of the buggy apps, but feel that the system ought to offer some protection against the Out Of Memory scenario (i.e. a program shouldn't be able to cause a system freeze simply by using too much memory.)
To solve this, I have been trying out Rik van Riel's OOM patch at "http://www.phys.uu.nl/~riel/patches/killer117.diff". It does the right thing in most cases and, as he has told me, it could certainly use more testing and fine-tuning. Will this or something like it appear in v. 2.2?
Regards,
Roy Bixler rcbixler@nyx.net
