>Description:
NFSv3 service stops functioning when large amount of data is written to FIFO in filesystem mounted from Solaris.

NFS client:

SunOS dev 5.7 Generic_106541-12 sun4u sparc SUNW,Ultra-4
>How-To-Repeat:
Write lots of data to a FIFO, with configuration described above.
"Small" amounts (that do not fill the Solaris internal buffers before getting read?) do not cause this effect.

>Fix:
Reboot the server.
