George Paul updated TS-88:
--------------------------
Attachment: TS88_patch1.diff
This patch 'TS88_patch1.diff' sets the process limits like 'RLIMIT_NOFILE' in
Traffic Manager when run as root before the TM changes to the configured
user&group.
Please review and let me know if there are any issues.
Tested on Ubuntu904 and Fedora11.

> When starting TS, i get a warning / error like this:
> [example_alarm_bin.sh] sent alarm: loki.ogre.com [Tue Dec 15 20:33:55 2009]
> connection throttle too high, 10000 (throttle) + 192 (internal use) > 8192
> (file descriptor limit), using throttle of 8000
> stracing traffic_manager, I see:
> r...@loki 332/1 # strace -f -e trace=setrlimit ./bin/traffic_manager 2>&1 |
> grep setrlimit
> [pid 24114] setrlimit(RLIMIT_CPU, {rlim_cur=RLIM_INFINITY,
> rlim_max=RLIM_INFINITY}) = 0
> [pid 24114] setrlimit(RLIMIT_FSIZE, {rlim_cur=RLIM_INFINITY,
> rlim_max=RLIM_INFINITY}) = 0
> [pid 24114] setrlimit(RLIMIT_NOFILE, {rlim_cur=1024, rlim_max=1024}) = 0
> [pid 24126] setrlimit(RLIMIT_CORE, {rlim_cur=0, rlim_max=0}) = 0
> [pid 24126] setrlimit(RLIMIT_NOFILE, {rlim_cur=10000, rlim_max=10000}) = -1
> EPERM (Operation not permitted)
> The last call is from traffic_server, indicating that it's not able to
> setrlimit() to 10000. This would only happen (I think) if at this point it's
> running as a non-root user. If I run traffic_server as root directly, I don't
> have this problem (i.e. when it calls setrlimit() as root, it works fine).
> This is using a standard installation in /usr/local.
