Subject: OpenSM 3.3.16 at 100% CPU load, "console off"
Date: Wed, 09 Oct 2013 13:10:28 +0200	[thread overview]
Message-ID: <525539A4.8090700@profitbricks.com> (raw)

Hi Hal,

we've encountered an issue with OpenSM 3.3.16 and the config option
"console off".
OpenSM processes are at 100% CPU load.

>From strace:
poll([{fd=0, events=POLLIN}], 1, 1000)  = 1 ([{fd=0, revents=POLLIN}])
read(0, "", 4096)                       = 0
poll([{fd=0, events=POLLIN}], 1, 1000)  = 1 ([{fd=0, revents=POLLIN}])
read(0, "", 4096)                       = 0
poll([{fd=0, events=POLLIN}], 1, 1000)  = 1 ([{fd=0, revents=POLLIN}])
read(0, "", 4096)                       = 0

As far as I've seen in the code, the function osm_console() from
opensm/osm_console.c is the only function which uses poll().

Is this issue already known or perhaps already fixed?

Thanks,
Sebastian
