To: linux-kernel@vger.kernel.org Cc: pgsql-hackers@postgresql.org MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Kernel 2.4.23 on redhat 8.0Please cc any response from linux kernel list. TIA. On or about 7:50am Friday 13 2004 my postgresql server breaks down. I can ssh and use "top" and "ps" but postgresql stops accepting connection. A small perl script that logs system load average also hangs. I cannot "kill -9" any hang processes including postgreqsql postmaster process. I then check dmesg and found error message that I copy and paste at the bottom. I finally issued reboot but reboot also didn't work and I had to push the reset button. AMD XP 2500+ with 1.5GB Memory. Postgresql data lives on a software raid 1 device. Kernel 2.4.23 on redhat 8.0 Postgresql 7.4 The last time server was rebooted was about 60 days ago when I upgraded the kernel Can someone suggest anything to help me avoid this type of breakdown? I tried to post the message yesterday but postgresql list wasn't responding at all to subscription request. ------------ swap_free: Bad swap file entry 00000004 kernel BUG at buffer.c:539! invalid operand: 0000 CPU: 0 EIP: 0010:[] Not tainted EFLAGS: 00010282 eax: cfd10a40 ebx: 00000002 ecx: e75f6ac0 edx: c02c548c esi: e75f6ac0 edi: 00000001 ebp: e75f6ac0 esp: f74efe60 ds: 0018 es: 0018 ss: 0018 Process postmaster (pid: 457, stackpage=f74ef000) Stack: 00000002 c01397ab e75f6ac0 00000002 e75f6ac0 00001000 c013a326 e75f6ac0 00001000 00000000 00420000 00000000 c2166b40 f7822980 c013aaef f7822980 c2166b40 00000000 00001000 c2166b40 f7822980 00001000 f7822a34 c016064c Call Trace: [] [] [] [] [] [] [] [] [] [] Code: 0f 0b 1b 02 17 e0 23 c0 8b 02 85 c0 75 07 89 0a 89 49 24 8b linux-kernel@vger.kernel.orglinux-kernel@vger.kernel.orglinux-kernel@vger.kernel.org __________________________________ Do you Yahoo!?
