A long time ago I set limits in /etc/security/limits.conf recently I have to run some independent firefox instances:
--8<---------------cut here---------------start------------->8--- for q in 1 2 3 4 5 6 7 8 9 10; do iceweasel -no-remote -P profile$q & ; done --8<---------------cut here---------------end--------------->8--- And some of them were killed by trap or segfault. I set limits bigger, and by limits conf looks like this: --8<---------------cut here---------------start------------->8--- sudo cat /etc/security/limits.conf [sudo] password for kjonca: * hard nproc 500 * soft nproc 150 kjonca - nproc 16000 --8<---------------cut here---------------end--------------->8--- I have relogged (I am using xdm, if it matters) but I can't run iceweasel instances --8<---------------cut here---------------start------------->8--- ps xms|wc --8<---------------cut here---------------end--------------->8--- gives me something like 480-490 so I suspect, that somehow is enforced another limit. BTW: --8<---------------cut here---------------start------------->8--- kjonca@alfa:~%ulimit -a -t: cpu time (seconds) unlimited -f: file size (blocks) unlimited -d: data seg size (kbytes) unlimited -s: stack size (kbytes) 8192 -c: core file size (blocks) 0 -m: resident set size (kbytes) unlimited -u: processes 16000 -n: file descriptors 65536 -l: locked-in-memory size (kbytes) 64 -v: address space (kbytes) unlimited -x: file locks unlimited -i: pending signals 128633 -q: bytes in POSIX msg queues 819200 -e: max nice 0 -r: max rt priority 0 -N 15: unlimited --8<---------------cut here---------------end--------------->8--- What should I check?
