Unfortunately, I don't think there are any workarounds right now, other than periodically restarting. We'll try to resolve the issue and get a fix into one of the next few releases.</p> <p>I apologize for the inconvenience. </p> http://www.datastax.com/support-forums/topic/opscenter-stops-working-after-several-hours-win-2008-server#post-7491 Tue, 13 Nov 2012 23:28:19 +0000 mikek753 7491@http://www.datastax.com/support-forums/ <p>sorry, are there any updates for this matter?<br /> Or should I consider Linux only for OpsCenter?</p> <p>So far I keep restarting OpsCenter 2-3 times / day</p> <p>thanks </p> http://www.datastax.com/support-forums/topic/opscenter-stops-working-after-several-hours-win-2008-server#post-7301 Wed, 31 Oct 2012 18:26:58 +0000 thobbs 7301@http://www.datastax.com/support-forums/ <p>This appears to be related to hitting an open file handle limit. This probably means there is some kind of handle leak, but if there's a way for you to raise the limit, that might help temporarily. I'll look into the issue to see if there's some kind of leak. </p> http://www.datastax.com/support-forums/topic/opscenter-stops-working-after-several-hours-win-2008-server#post-7212 Tue, 30 Oct 2012 15:05:29 +0000 mikek753 7212@http://www.datastax.com/support-forums/ <p>hi experts,</p> <p>Cassandra (multi nodes) and OpsCenter are installed and running on Win 2008 servers.<br /> When OpsCenter starts it works Ok, however after an hour or two it stops.<br /> I see the same error in opscenter log</p> <p>2012-10-30 07:51:52-0700 [] INFO: Malformed file descriptor found.
