Hi, I found the following in the logs of a server that crashed: Mar 19 14:09:28 sc4 kernel: Assertion failure in ext3_free_blocks() at balloc.c line 358: "bh->b_committed_data != NULL" Mar 19 14:09:28 sc4 kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000000 Mar 19 14:09:28 sc4 kernel: current->tss.cr3 = 39b8b000, %%cr3 = 39b8b000 Mar 19 14:09:28 sc4 kernel: *pde = 00000000 Mar 19 14:09:28 sc4 kernel: Oops: 0002 Mar 19 14:09:28 sc4 kernel: CPU: 0 Mar 19 14:09:28 sc4 kernel: EIP: 0010:[ext3_free_blocks+616/772] Mar 19 14:09:28 sc4 kernel: EFLAGS: 00010282 Mar 19 14:09:28 sc4 kernel: eax: 00000060 ebx: c009c600 ecx: ffffffff edx: 0000003c Mar 19 14:09:28 sc4 kernel: esi: 00000adc edi: 00000000 ebp: d57773a0 esp: f972de58 Searching through the ext3 mailing list I found the following post which had a similar experience: http://www.redhat.com/mailing-lists/ext3-users/msg02666.html However, there was no reply to his query. The server in question runs squid which handles high volume of traffic every day. Debian 2.2 (potato) kernel 2.2.19 ext3-0.0.7 1024 MB RAM Pentium III 850 Mhz squid 2.4.STABLE4 Any help is much appreciated. Btw, would changing the kernel to 2.4.x help in this situation? Rgds, Meng Kuan
