Some additional information from my investigations.
The basic problem was that this issue suddenly cropped up (after years
of running fine) and had become a daily issue, with no hope of Vendor
support, but WHY did it suddenly become a daily issue.
After some investigation I determined that a new "logging" process
which was implimented to track down problems with TAXWARE is probably
the root of the problem.
The logging process, at peak hours, is generating 10,000 - 12,000
files per hour into a directory on DSA15. In conjunction with this,
there is a Purge process which is moving any logs more than two hour
old to an archive, the purge runs hourly. To avoid the over head
of physically moving the data, the purge simply renames the files to a
different directory.
Unfortunately, DSA15 is also the location some of the FAXSR
directories, containing Forms, Cover Pages, Bitmaps, etc., and most
importantly, the FAXSR$FAXES directory. This directory is almost
always empty, however is is used by the FAXSR composer as a "work"
directory, where the out-going FAX is "built", or composed. Once
the fax is sent, it is deleted from the FAXSR$FAXES directory.
Although at peak times there is are very high File-Creation and IO
rates to this disk, there is no correllation between Composer
terminations and Peak Work times. The disk IO queue does not show
any particular strain.
My suspicion regarding the Logging process is simply based on the fact
that
Logging started on 16th Jan
First problem was on 17th Jan (twice), then the 20th (3)
Logging was stopped on 20th, (no further issues)
Logging restarted on 24th
Problems started again. 25th (3), 26th (3), 27th (3), 28th (17),
30th, (1), 31st (1), 1st Feb (2), 2nd (2).
Logging stopped on Feb 2nd
No incidents since.
It seems pretty open and shut. What I dont understand is the
mechanism that could cause this kind of interference (and without
access to the code, I dont expect anyone to tell me). It does
however appear that the error message "Disk space too low -
terminating" is most likely a red-herring.
Thanks to all who contributed to the thread, and I just hope this is
of use to anyone who comes up against the same issue.
Dave.
