Subject: NFS mounting and channel access

Has anyone seen the following problem:

We're using Epics 3.12 on a Heurikon Nitro60 IOC with vxWorks 5.2,
and when not using NFS mounting, all seems normal.
However, when using the NFS mounting and channel access to invoke a
function on the IOC, we've gotten a variety of errors involving 
channel access after we write to a file through the NFS mount.
Invoking the function directly from the vxWorks shell 
does not create a problem.
This problem occurs with a Dec Alpha running Epics 3.12 as well as with
a Sun Sparc2 running Epics 3.11.

For example, here is some of the vxWorks output:

CA event: A call to "assert (0)" failed in ../caserverio.c at 143
Please send a copy of the output from "tt (0xcce09c)" and a copy of this message
to the author or "[email protected]"

e7a32e _epicsAssert   +56 : _taskSuspend (cce09c)
value = 0 = 0x0



Any help would be greatly appreciated.
