:
:I just got a new sort of deadlock on a NFS server.
:
:During the extraction of a tarball archive by a FreeBSD client, the server
:became unresponsive.
:
:It could still answer to pings but all other sort of network activity failed.
:Ssh sessions were hanged, there was no answer to telnet commands, etc...
:...
:On the console there was a single message:
:
:	Warning, objcache(mbuf pkt hdr): Exhausted!

    How much memory does the server have?  What does 'netstat -m' say
    on the server?
