[hylafax-users] Problems with blocked faxes

[Justin Hendrickson <jhendric@xxxxxxxxxxxxxxxx>]

Every night I have a large stack of faxes being sent. Frequently, some
of those faxes are going to the same number, so some get blocked due to
concurrent calls. After whatever delay HylaFax assigns to a blocked
call, almost all of the blocked faxes are eventually sent out
successfully. Here's an example of one such faxes syslog entries:


Nov 12 15:58:14 localhost FaxQueuer[5186]: SUBMIT JOB 27316
Nov 12 15:58:16 localhost HylaFAX[18350]: Filesystem has SysV-style file
creation semantics.

"blocked" ""

Nov 12 16:31:16 localhost FaxQueuer[5186]:
NOTIFY: /var/www/bravoforms/scripts/hylafax_notify.php "doneq/q27316"
"done" "1:54"


Unfortunately, there's always a couple of stubborn ones that never seem
to become unblocked. Here's an example of one such blocked faxes syslog
entries:


Nov 12 16:00:28 localhost FaxQueuer[5186]: SUBMIT JOB 27340
Nov 12 16:00:29 localhost HylaFAX[18753]: Filesystem has SysV-style file
creation semantics.
Nov 12 16:00:29 localhost HylaFAX[18753]: What we have here is a PDF
file
Nov 12 16:25:12 localhost FaxQueuer[5186]:
NOTIFY: /var/www/bravoforms/scripts/hylafax_notify.php "sendq/q27340"
"blocked" ""
Nov 13 05:00:17 localhost FaxQueuer[29723]:
NOTIFY: /var/www/bravoforms/scripts/hylafax_notify.php "sendq/q27340"
"blocked" ""


Note: cron restarts the HylaFax server at 5AM every day.

As you can see, the fax blocked at 4:25PM and never sent until the
HylaFax server was restarted.

Does anyone know why this would happen?
