Hi list, We have a backup server Dell Power Edge 1850, One Xeon 3.6 Ghz, 2GB Ram, attached to one storage PowerVault 220 and one LTO tape drive, running STABLE from start of June. This machine basically runs FTP Server, NFS Server, compress directories using tar and gzip and run some perl scripts. Some from now this machine is presenting random freezes, then I compiled a kernel with: makeoptions DEBUG=-g options KDB options DDB options INVARIANTS options INVARIANT_SUPPORT options WITNESS options DEBUG_LOCKS options DEBUG_VFS_LOCKS options DIAGNOSTIC yesterday the machine freeze completely, no ping, no keyboard response, I have to do a hard reset (hold power off button) to bring this back. Today happened again and this time they break to debbuger and I can get a dump that follow. Excuse-me by sending images. This is because I don't have a serial cable to plug on the machine, they are on a Datacenter and usually I have only remote access. http://www.seudns.net/~ale/crash/page_fault.jpg http://www.seudns.net/~ale/crash/bt.jpg http://www.seudns.net/~ale/crash/ps_1.jpg http://www.seudns.net/~ale/crash/ps_2.jpg http://www.seudns.net/~ale/crash/ps_3.jpg http://www.seudns.net/~ale/crash/ps_4.jpg http://www.seudns.net/~ale/crash/ps_5.jpg http://www.seudns.net/~ale/crash/ps_6.jpg http://www.seudns.net/~ale/crash/ps_7.jpg http://www.seudns.net/~ale/crash/show_allcpu.jpg http://www.seudns.net/~ale/crash/show_alllocks.jpg http://www.seudns.net/~ale/crash/show_lockedvnodes.jpg http://www.seudns.net/~ale/crash/show_lockedvnodes_2.jpg http://www.seudns.net/~ale/crash/show_lockedvnodes_3.jpg ======== dmesg =======Copyright (c) 1992-2007 The FreeBSD Project.
