Hi,

we use a DFS-NFS-Gateway on AIX 5.1 as our NFS-Server. This works fine most of 
the time but for four months we have strange problems. There are basically 
two issues:

1. Using "ls" in specific directories after certain idle time gives us 
an "Input/Output Error" without any results.

2. In some directories some entries are not shown. For example there is a 
directory with the subdirectory ak_fcp in it. "ls" does not show this 
directory. But it is possible to do "cd ak_fcp" and then normally work with 
it.  It is also possible to access files in the directory while being in the 
parent directory: " less ak_fcp/logfile"  works.

Does anybody know how to get rid of the problems? The problems occur on 
several different linux versions.

Greetings
Christoph
