Corona,
Thanks for the tip. I got it working finally, the Perl code was so old that it was not using the proper semantics to invoke fcntl type locking. Once that was fixed, and really suprising just one initializatin script that all of scripts called, everything works.
I am still puzzled about why when the Ubuntu machine was serving the files it worked and when I switch the having CentOS server the files it stopped working.
Maybe something to do with the CentOS machine using NFSv4 even though the Solaris machine was mounting the filesystem as version 3?

Hi,
Simple question but I just need to confirm the answer:
If two or more processes attempt to move the same file at exactly the same time, will unix internal file locking allow only one of the processes to access the file?
Many thanks

SYSTEMD-MACHINE-ID-COMMIT.SERVICE(8) systemd-machine-id-commit.service SYSTEMD-MACHINE-ID-COMMIT.SERVICE(8)
NAME
systemd-machine-id-commit.service - Commit a transient machine ID to disk
SYNOPSIS
systemd-machine-id-commit.service
DESCRIPTION
systemd-machine-id-commit.service is an early boot service responsible for committing transient /etc/machine-id files to a writable disk
file system. See machine-id(5) for more information about machine IDs.
This service is started after local-fs.target in case /etc/machine-id is a mount point of its own (usually from a memory file system such
as "tmpfs") and /etc is writable. The service will invoke systemd-machine-id-setup --commit, which writes the current transient machine ID
to disk and unmount the /etc/machine-id file in a race-free manner to ensure that file is always valid and accessible for other processes.
See systemd-machine-id-setup(1) for details.
The main use case of this service are systems where /etc/machine-id is read-only and initially not initialized. In this case, the system
manager will generate a transient machine ID file on a memory file system, and mount it over /etc/machine-id, during the early boot phase.
This service is then invoked in a later boot phase, as soon as /etc has been remounted writable and the ID may thus be committed to disk to
make it permanent.
