Re: [hylafax-users] sendfax sometimes hangs, can't identify protocol?

Hm.. if sendfax and faxstat are the *only* clients you use, then the
trigger bug doesn't sound likely. Are there any faxq messages in syslog
about "Bad fifo message" or something like that?
Bingo. There is indeed some very usefull information in syslog (I
think). Two sendfax processes I had to kill today were process ID's
26875 (the example from my previous mail), and 8693. In syslog there are
lots of FIFO errors, but what surprises me are these lines:
May 8 11:42:36 caracas FaxQueuer[3699]: HylaClient::send: /26876:
Cannot open FIFO: No such file or directory
and
May 8 12:03:53 caracas FaxQueuer[3699]: HylaClient::send: t/8694:
Cannot open FIFO: No such file or directory
The numbers here are the killed sendfax ID's + 1. The times are indeed
the times on which the hanging sendfax processes were started. Do you
know what this all means?
Here is the contect of the two lines:
cat /var/log/syslog|grep -i fifo|grep -v 'not found':

I had to do a grep -v 'not found' because my syslog file contains a huge
amount of lines like
May 8 09:23:15 caracas FaxQueuer[3699]: FIFO: JOB 27891 not found for
msg "D22,1,212029,000034734,"docq/doc27933.pdf;01""
I don't know what that means, but apparently it's not important. I never
experience problems form them.
Well, you're in luck. You can build debian packages right from CVS:
