Hi Andrew,

could it be that this introduced an fd leak? running a kernel of 20080405
with a large bacula backup slowly brought the machine into trouble.
processes where waiting mostly on vm_map and vmstat -m showed
following values for fdfile:

Name        Size Requests Fail Releases    Pgreq Pgrel   Npage    
Hiwat       
fdfile           64 10449800     0     18518 165580        4 165576   165576

This is an awful lot of fdfile structures.

Regards,
 Frank
