Re: Problem with MySQL and SMP?
Any suggestions on loging tools I cna run to try to find out more information? The machine is coloced about 3 hours for me, so I would hate to have to drive there and install FreeBSD on it, when it was just something I could have fixed.

Re: Problem with MySQL and SMP?
We are having the same problem. Mandrake 8.1, kernel 2.4.17, MySQL 3.23.47. Dual PIII-500, 512MB of RAM, Mylex DAC960 RAID 5. After being up for a few days, the system completely froze. No ssh, no console, nothing. Had to hard reset the server. Yes, we compiled MySQL: we have to. Our application relies on SELECT id ... WHERE id IS NULL behaving the same way as LAST_INSERT_ID(), and to do that, I have to comment out one (yes, just one) line of code. Which means I have to compile.

RE: Problem with MySQL and SMP?
Forgot to say I was running MySQL v 3.23.39 Also, I read in one of the other messages on this thread that the problem might be RedHat. I don't relly belive this because a kernel is a kernel. RedHat = Every other Distro when it comes to issues with the kernel (memory,diskaccess,etc). In my opinion, I have been wrong before. - Johnny Withers [EMAIL PROTECTED] p. 601.853.0211 c. 601.209.4985 -Original Message- From: Johnny Withers [mailto:[EMAIL PROTECTED]] Sent: Friday, January 11, 2002 11:40 AM To: 'MySQL' Subject: RE: Problem with MySQL and SMP?

Try: http://lists.mysql.com/php/unsubscribe.php Perhaps your problem lies in the IDE controller. For some reason, my friend and I have been through several dual (MSI Tyan) motherboards over the past few months that have almost always had IDE controller problems where they wouldn't work at all, or would lock up after using them for 20 to 30 minutes. If you're using IDE on the dual, try SCSI. Or perhaps the chipset? Did you use the same motherboard in both SMP servers? If so, perhaps there was a chipset problem in that brand, and you may have to check with the manufacturer. I'm just taking shots in the dark here, but there's no reason why the SQL server should keep crashing ONLY because the difference is single processor kernel, or smp kernel. I would assume that any good SQL server is designed with SMP kernel in mind for database apps that would require a lot of processing power. Try eliminating the possibilities of hardware problems first.
