>Description:
This machine was stable for years, but is experiencing constantly
crash every 3 days after upgrading to 4.0-STABLE.
This is a heavy-loaded server for all kinds of FreeBSD service.
The panic message is "vrele: negative ref cnt", but previous 2
panic messages were both "vdrop: holdcnt".
gdb output is followed :
GNU gdb 4.18
