Then it should be the environment at fault.
I believe that the 145 errno is, per combination of the lstat man page and
IRIX errno list:

   ETIMEDOUT The named file is located on a remote file system which is not
             available

It might even be a responsiveness problem with a local file system.
Watch for things like NFS mount points in the midst of the file system,
with the foreign file server not being responsive.
The backup log might indicate the file system area where this is occurring,
and therewith the cause may be apparent.  If not, I would do:
   find <FilesysName> -ls
to run the filesystem seeking the faulty area.
As always, check the opsys error log for any obvious problem indications.
