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?
