West </div><div><br></div><div><b><span class="Apple-style-span" style="text-decoration: underline;">What For:</span></b></div><div>This was found to be a compounded problem. (Cisco was part of it... But the real problem was the linux kernel...)</div><div>Suffice it to say, without the kernel bug, the cisco bug wouldn't have been easily found.</div><div><br></div><div><b><span class="Apple-style-span" style="text-decoration: underline;">What Kernel Bug:</span></b></div><div>It's a kernel bug that corrupted the sqlite database.</div><div>This caused Freeswitch to refuse the phones registration request.</div><div>This in turn caused the phones to re-register.</div><div>Problem was, with 10 phones, 6 lines each, perpetually registering on a 100Mbps LAN, well, you can imagine the overhead.</div><div>This created severe latency with Freeswitch, and manifested as dropped calls, one way audio, and the more phones you had, the worse the problem was.</div><div><br></div><div>Workaround for problem was to use a ramdisk (tmpfs) for the database - (Big Thanks to bkw!)</div><div><br></div><div>So far, it's been 24 hours, and all systems are nice and stable. (no negative reports yet (fingers crossed)).</div><div><br></div><div>Brian (and Folks);</div><div>If this is stable through Friday (and there's no reason to think it won't be), I will take the time to document the problem, basic configuration, and the workaround for the problem on the Wiki this weekend.</div><div><br></div><div>
