Dear folks I'm using 2.0.5-ALPHA on the following system. CPU: 80486 DX2/66MHz Memory: 16MB Peripherals: IDE 340MB internal hard disk SCSI 2GB external hard disk (via AHA-1542Cx ) elete 16 ether board This machine serves as a news server & a mail server, so, exports a partition which holds system mailbox. This machine tends to crash once a day or once an hour, so, I configured to make crash dump. From a crash dump, I obtained following backtrace. Reading symbol data from /h0/ohki/crash/kernel.0... (no debugging symbols found)...done. IdlePTD 1cc000 panic: vm_object_deallocate: object deallocated too many times current pcb at 1bce1c (kgdb) bt #0 0xf018ee90 in boot () #1 0xf0113683 in panic () #2 0xf0185a95 in vm_object_deallocate () #3 0xf015da59 in nfsrv_vrele () #4 0xf0153637 in nfsrv_link () #5 0xf015e613 in nfssvc_nfsd () #6 0xf015df1a in nfssvc () #7 0xf0193ef7 in syscall () (kgdb)
