Re: FreeBSD 5.3 SMP freezes with MySQL 4.1
I had repeated the panic by reset debug.mpsafenet from 0 to 1, after that, the system automatically reboot after several hours, and if debug.mpsafenet was set to 0, the system is stable. so i guess this is a tcp stack or NIC driver SMP thread-safe issue, normally my server got over 1000 interrupts/s on bge, I have plan to replace the onboard bge NIC to fxp and set debug.mpsafenet to 1 to see what will happen this week. -- Young Lee On Thu, 31 Mar 2005 18:03:08 +0200 Uzi Klein [EMAIL PROTECTED] wrote: Young Lee wrote: Thank you very much.

I just did the exact same thing: disable motherboard bge in preference to em (intel) on a PCI card, and have had 100% stable for the last 6 days. Normally every night during heavy network backup and database reporting the bge ports would either be reset after watchdog timeout, or the whole system would freeze with nothing logged to console, screen, or BIOS... so going 6 days without any events leads me to point a big hairy finger at bge driver. Even with mpsafenet=0, I was having these timeouts and lockups, and bad performance thrown in. :-( I run with mpsafenet default and the em ethernet driver. Be sure to disable the onboard bge in your BIOS. I'm on a dual opteron Tyan S2881 motherboard, for what that's worth. FreeBSD 5.4-STABLE from April 4 is my OS. My guess is with the intel NIC you will find yourself much more stable. On my lesser loaded machines the bge driver holds up ok. Vivek Khera, Ph.D. +1-301-869-4449 x806

Re: FreeBSD 5.3 SMP freezes with MySQL 4.1
I have try your solution yesterday, so far it is stable, and will observe the stability for some days. btw, i turn debug.mpsafenet=0 in /boot/loader.conf to evade the possible network stack deadlock under SMP. -- Young Lee On Tue, 29 Mar 2005 11:26:59 +0200 Uzi Klein [EMAIL PROTECTED] wrote: Young Lee wrote: as I said , I build mysql41-server from port without any parameters, so you can see libwrap, and i will --without it next time. the smp kernel should be crashed in 2 minutes, so my server is running with UP configuration, and the SMP dmesg wasn't saved.

There's just not enough information to tell. When you say freeze, is the machine totally unresponsive, or does the console allow you to type characters? Can you ping the system when it appears frozen?

Which thread options did you use in the port config? Please post your dmseg, mysql log, mysql slow query log. When I build the kernel without SMP, the system is stable. I have try 5.3-p5 and 5.4-PRE, the problem is still there. It's my configuration mistake or will be solved in 5.4-RELEASE ?
