Hi, I'm new here and I'm not sure whether this should be reported here. OS: CentOS 2.6.9-67.0.15.EL Memory: 512M Python Version: 2.5.1 The crash happened after our web program writen with python running for many days (maybe 20 days). Here are the logs I found in /var/log/messages Jul 14 04:30:38 kernel: Unable to handle kernel NULL pointer dereference at virtual address 00000002 Jul 14 04:30:38 kernel: printing eip: Jul 14 04:30:38 kernel: 00000002 Jul 14 04:30:38 kernel: *pde = 0c223067 Jul 14 04:30:38 kernel: Oops: 0000 [#1] Jul 14 04:30:38 kernel: Modules linked in: ipt_state ipt_TOS iptable_mangle ip_conntrack_ftp ip_conntrack_irc ip_conntrack ipt_REJECT ipt_LOG ipt_limit iptable_filter ipt_multiport ip_tables autofs4 sunrpc loop dm_mirror dm_mod ohci_hcd ehci_hcd k8_edac edac_mc snd_atiixp snd_ac97_codec snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd soundcore snd_page_alloc tg3 floppy ext3 jbd sata_sil libata sd_mod scsi_mod Jul 14 04:30:38 kernel: CPU: 0 Jul 14 04:30:38 kernel: EIP: 0060:[<00000002>] Not tainted VLI Jul 14 04:30:38 kernel: EFLAGS: 00010202 (2.6.9-67.0.15.EL) Jul 14 04:30:38 kernel: EIP is at 0x2 Jul 14 04:30:38 kernel: eax: c11bf760 ebx: c11bf760 ecx: c11bf760 edx: 00000002 Jul 14 04:30:38 kernel: esi: 00000000 edi: 0000c000 ebp: c5a2e1a8 esp: c7198ecc Jul 14 04:30:38 kernel: ds: 007b es: 007b ss: 0068 Jul 14 04:30:38 kernel: Process python (pid: 16598, threadinfo=c7198000 task=c8cccbd0) Jul 14 04:30:38 kernel: Stack: c01514ee c015ab59 0dfbb067 00080000 1ec5e000 c0411074 1ec5e000 1ecde000 Jul 14 04:30:38 kernel: d3a2e1f0 c0411074 c015ac29 00080000 00000000 1ec5e000 d3a2e1f0 1ecde000 Jul 14 04:30:38 kernel: c0411074 c015ac88 00080000 00000000 c7198f7c 1ec5e000 cd708b4c 1edac000 Jul 14 04:30:38 kernel: Call Trace: Jul 14 04:30:38 kernel: [] set_page_dirty+0x2c/0x41 Jul 14 04:30:38 kernel: [] zap_pte_range+0x191/0x21f Jul 14 04:30:38 kernel: [] zap_pmd_range+0x42/0x65 Jul 14 04:30:38 kernel: [] unmap_page_range+0x3c/0x5f Jul 14 04:30:38 kernel: [] unmap_vmas+0xf1/0x1df Jul 14 04:30:38 kernel: [] unmap_region+0x61/0xc6 Jul 14 04:30:38 kernel: [] do_munmap+0x144/0x1b1 Jul 14 04:30:38 kernel: [] sys_munmap+0x51/0x68 Jul 14 04:30:38 kernel: [] syscall_call+0x7/0xb Jul 14 04:30:38 kernel: Code: Bad EIP value.

Run out of memory? Please tell me what I can do. Regards YiYuan

This is a Linux kernel crash, and has nothing to do with Python. No matter what errors Python or your script may have - the operating system kernel should not crash. Please report this in a Linux forum, or try to upgrade to a newer kernel.
