> We have implemented a faxserver using LPRng. The faxing is currently
> done using a printfilter and has been working quite well on another
> machine for some time.
>
> We started developing a problem in which LPRng would "drop"
> faxes/printjobs. I.e. We could send 2500 "faxes/printjobs" to a
> specific queue, and we would lose a percentage of them. We had since
> put in enough "checking" so that the queue couldn't really get
> overloaded too badly.
>
> I am now trying to implement a new faxserver (using LPRng 3.8.4 and SuSE
> 7.3), but I have run into a couple of problems.
>
> At first, I started receiving Open_gdbm errors (using the stock LPRng
> 3.7.4 with SuSE), and have since stepped up to 3.8.4 building it
> myself. The Open_gdbm errors have disappeared (from what I can tell,
> I'm not 100% sure of this because another problem has made itself more
> apparent). I also increased /proc/sys/fs/file-max to 16384.
Yes, cause I ripped the code for this out.

This is to make Samba and other systems (such as the new IPP protocol
support) happy, cause they want to see what happened to the jobs
that they submitted.
>From the 'CHANGES' file:
Version LPRng-3.8.2 - Mon Dec 3 12:26:52 PST 2001
MAJOR CONFIGURATION CHANGE:
LPRng can retain status of last N completed jobs
configure --with-done_jobs=N
- set done_jobs value, default 1
configure --with-done_jobs_max_age =N
- set done_jobs_max_age value, default = 0 (no expiry)
Or in the printcap/lpd.conf:
:done_jobs=1
:done_jobs_max_age=1
Example:
Printer: t1@h110 'Test Printer 1'
Queue: no printable jobs in queue
Server: no server active
Status: job 'cfA231h110.private' removed at 18:25:36.281
Rank Owner/ID Class Job Files Size Time
done papowell A 278 /tmp/hi 3 18:25:31
Controlled by:
:save_on_error - all jobs with error saved, status not removed
:save_when_done - all jobs with no error saved, status not removed
:done_jobs=N - last N jobs completed (error or no error) saved
:done_jobs_max_age=N - jobs with status older than N seconds removed
This is best explained by:
On job completion:
if( (no error && save_when_done)
|| (error && save_on_error)
|| done_jobs > 0 || done_jobs_max_age > 0 ){
do not remove job
}
When queue updated:
if( !(save_on_error || save_when_done) ){
while( done_jobs_max_age >= 0
&& the time since completion of oldest done job > done_jobs_max_age ){
remove the oldest done job
}
while( done_jobs >= 0 && total number of done jobs > done_jobs ){
remove the oldest done job
}
}
You can set:
fax:done_jobs=0:done_jobs_max_age=0
to disable this operation.
Actually, most folks LIKE this, otherwise I would not have put it in.

> Also, the "fax" queue hands off the printjobs to 17 other fax devices to

> full, or same fax number, or print it, or e-mail as a pdf).
