Re: st: repeated (bogus?) license file error message
Pann McCuaig (email@example.com) asked about an error message
related to license-tracking in Stata:
> Stata is running on a cluster of nine Sun multi-Opteron boxes running
> Scientific Linux 4.3. Normal /usr/local install. /use/local is local to
> one of the nine boxes and is NFS-exported to the other 8.

This error can arise due to NFS caching. NFS caching can result in
different servers seeing inconsistent versions of the same file. When
this happens, Stata on one server might use the same license position
for a user as Stata on another server uses for a different user. This
in turn can lead to the error Pann is seeing.
Pann should use the
flag when issuing the -mount- command in Unix to disable read and write
caching, which should solve the problem.
If the error persists, Pann should contact Stata Technical Services
at <firstname.lastname@example.org> for more help in tracking down the source
of the error.
