SunOS 4.0.1 NFS Caching Bug?

[David Hull]

Has anyone noticed that under SunOS 4.0.1 it sometimes takes a long time
for file status information to get propagated from an NFS server to its
clients?

In the following example, popeye and zeke are both running 4.0.1.

popeye% pwd
/home/popeye/david
popeye% touch foo

zeke% pwd
/home/popeye/david
zeke% df .
Filesystem            kbytes    used   avail capacity  Mounted on
popeye:/home/popeye   496983  411736   35548    92%    /home/popeye
zeke% ls -l foo
-rw-r--r--  1 david           0 Jun  5 17:28 foo

popeye% echo hello >> foo

zeke% ls -l foo
-rw-r--r--  1 david           0 Jun  5 17:28 foo
[ thirty seconds later ]
zeke% ls -l foo
-rw-r--r--  1 david           0 Jun  5 17:28 foo
zeke% ls -l foo
-rw-r--r--  1 david           6 Jun  5 17:29 foo

I tried setting acregmax and acdirmax to 0 in zeke's fstab, but it made
no difference.
