One of our servers was panicing once every several days for the past few months. It is an Asus P2B-S PII 450Mhz 512M RAM. It was sync with 3.2-stable within a week. I replaced all its hardware components (MB, CPU, RAM, controllers) except the set of disk drivers. I could not get a core dump, since it would hang on after the 'disk sync...'. Here are the ddb trace from the last 2 panics: ----- db> trace Debugger(c022c083) at Debugger+0x37 panic(c0236c12,c78e1000,ca98d780,c0264904,c78e1000) at panic+0x74 vm_fault(c0264904,c78e1000,3,0,ca98d780) at vm_fault+0x122 trap_pfault(ca9a1bf0,0,c78e100c,80000000,ca9a1cd4) at trap_pfault+0xf0 trap(c01d0010,cae10010,c78e100c,ca9a1cd4,ca9a1c98) at trap+0x332 calltrap() at calltrap+0x1c --- trap 0xc, eip = 0xc0209dda, esp = 0xca9a1c2c, ebp = 0xca9a1c98 --- generic_bcopy(cae15300,cab3f180,ca9a1cd4,ca9a1f28,0) at generic_bcopy+0x1a ufs_makeinode(81b4,cae15300,ca9a1f14,ca9a1f28) at ufs_makeinode+0x184 ufs_create(ca9a1e30,ca9a1ea4,c0170d87,ca9a1e30,0) at ufs_create+0x26 ufs_vnoperate(ca9a1e30,0,ca9a1f94,ca98d780,c1db1a80) at ufs_vnoperate+0x15 vn_open(ca9a1f04,602,1b4,ca98d780,c0248388) at vn_open+0x11b open(ca98d780,ca9a1f94) at open+0xad syscall(bfbf0027,bfbf0027,8065919,80fb121,bfbfc4c8) at syscall+0x127 Xint0x80_syscall() at Xint0x80_syscall+0x2c ----- db> trace Debugger(c022c083) at Debugger+0x37 panic(c0236c12,c6e0a000,ca98d200,c0264904,c6e0a000) at panic+0x74 vm_fault(c0264904,c6e0a000,1,0,ca98d200) at vm_fault+0x122 trap_pfault(ca9bf9e0,0,c6e0abd4,80000000,c1d66c00) at trap_pfault+0xf0 trap(10,c1d60010,5bd0,c1d66c00,ca9bfaa0) at trap+0x332 calltrap() at calltrap+0x1c --- trap 0xc, eip = 0xc01de043, esp = 0xca9bfa1c, ebp = 0xca9bfaa0 --- ufs_lookup(ca9bfadc,ca9bfaf0,c01675e4,ca9bfadc,caa80007) at ufs_lookup+0x25f ufs_vnoperate(ca9bfadc,caa80007,caae9780,ca9bfdbc,c01e2e55) at ufs_vnoperate+0x1 5 vfs_cache_lookup(ca9bfb38,ca9bfb48,c0169a95,ca9bfb38,0) at vfs_cache_lookup+0x24 8 ufs_vnoperate(ca9bfb38,0,ca9bfdbc,ca9bfd98,caae9780) at ufs_vnoperate+0x15 lookup(ca9bfd98,0,c2186a84,0,7) at lookup+0x2c1 nfs_namei(ca9bfd98,ca9bfd10,1,c1b69e00,c1d50e50) at nfs_namei+0x34d nfsrv_lookup(c2186a00,c1b69e00,ca98d200,ca9bfe38,0) at nfsrv_lookup+0x42b nfssvc_nfsd(ca9bfe98,8075410,ca98d200,ca98d200,c0248838) at nfssvc_nfsd+0x4fe nfssvc(ca98d200,ca9bff94) at nfssvc+0x549 syscall(27,27,14,0,bfbfddc4) at syscall+0x127 Xint0x80_syscall() at Xint0x80_syscall+0x2c ---- I am kind of at a lost in what to do next.
