It's happening again :-( So this might be a NFS bug...

My www server running 1.6.1 without NFS (uptime 80+ days):

39 mbufs in use:
         20 mbufs allocated to data
         19 mbufs allocated to packet headers
53/62 mapped pages in use
196 Kbytes allocated to network (71% in use)
0 requests for memory denied
0 requests for memory delayed
1286 calls to protocol drain routines

The trouble maker running 1.6.1_STABLE (uptime 1+ days):

58469 mbufs in use:
         58461 mbufs allocated to data
         7 mbufs allocated to packet headers
         1 mbufs allocated to socket names and addresses
156/164 mapped pages in use
14964 Kbytes allocated to network (99% in use)
0 requests for memory denied
0 requests for memory delayed
54 calls to protocol drain routines
