http://openib.org/bugzilla/show_bug.cgi?id=229 --- Comment #6 from [EMAIL PROTECTED] 2006-10-09 23:14 --- I think Cisco SM is dropping ports which do not answer its queries, opensm does not, which is why things still work with opensm even if the mad thread goes inactive for a while. BTW, the renice is currently done upon openibd start - could you test this works correctly for you? --- You are receiving this mail because: --- You are the assignee for the bug, or are watching the assignee. ___ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general

http://openib.org/bugzilla/show_bug.cgi?id=229 --- Comment #3 from [EMAIL PROTECTED] 2006-09-11 23:14 --- Put email in bugzilla: Hmm, OK. I'd like to figure out whether this could be something other than a scheduler issue. Could you test on kernel 2.6.18 or 2.6.17 please? If this is a scheduler issue, there's a chance scheduler is more fair there. Quoting r.
