hammer + nfs => Input/output error

[Matthew Dillon]

:Using HAMMER for nfs exports, nfs client often get in a state
:where access to most files return `Input/output error' (EIO state).
:
:Example:
: - nfs server using HAMMER for all exports
: - nfs client mount of usr/src and /home/thomas (/usr/obj local)
:When building & installing world & kernel /home/thomas often get in `EIO st=
:ate'.
:/home/thomas is only lightly used (contrary to /usr/src).
:Only known solution (besides reboot) is remounting /home/thomas.
:
:When this happens nfs server log error (multiple times):
:lookupdotdot failed 2 dvp 0xca3087d0
:
:Is core dump needed?
:(will decrease hw.physmem; 2G now)
:
: -thomas

    What is the client?  DragonFly?  Linux?  FreeBSD?
