Re: [Freeswitch-users] A real puzzler for you guys... (perpetual registration causes denial of service.)
This is a well known and documented problem already fixed in upstream kernels. There was quite a bit of discussions about tests that came out that showed this issue. Opening another bug on it is not likely to help.

Re: [Freeswitch-users] A real puzzler for you guys... (perpetual registration causes denial of service.)
No penguin is perfect... There's issues w/ 2.6.X - 2.6.27.X with respect to timing for things like packet shaping, which is a requirement for me. 2.6.29.X onward, well, I might be inclined to try the latest revision, but last I tested was 2.6.30, and it was truly all round badness, with everything. They seem to have the IRQ handling problems re-worked, but even if you compile WITHOUT dynamic ticks, it's still horrible on the CPU. I'll wait until 2.6.32... What I got now is working w/ the workaround. Thanks Brian. (thinking to self, you know... Maybe there's a reason for the bias of these BSD zealots It ran fine on my old 11/780 which doubled as a forced air furnas...) Best Regards, Karl J.

The data in the sqlite db doesn't need to survive a reboot? Any benefit if it does? Also, I've read that the ramdisk isn't that different than what the kernel already does to keep things in memory (yielding very little gain). Thoughts on this?

Re: [Freeswitch-users] A real puzzler for you guys... (perpetual registration causes denial of service.)
Folks; I give credit where credit is due, and I thank Brian K. West What For: This was found to be a compounded problem. (Cisco was part of it... But the real problem was the linux kernel...) Suffice it to say, without the kernel bug, the cisco bug wouldn't have been easily found. What Kernel Bug: It's a kernel bug that corrupted the sqlite database. This caused Freeswitch to refuse the phones registration request. This in turn caused the phones to re-register. Problem was, with 10 phones, 6 lines each, perpetually registering on a 100Mbps LAN, well, you can imagine the overhead. 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. Workaround for problem was to use a ramdisk (tmpfs) for the database - (Big Thanks to bkw!) So far, it's been 24 hours, and all systems are nice and stable. (no negative reports yet (fingers crossed)). Brian (and Folks); 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.
