asterisk users - May 2005 - Outgoing spool file ignored

Hi list,

I'm using asterisk to send alerts via phone or fax, by using the spool 
functionnality (writing files in /var/spool/asterisk/outgoing). The 
system works, but sometimes a file in the outgoing directory is simply 
ignored by asterisk (nothing on the cli); the spool file is correct.
It happenned only twice since the system is installed (about two 
months), but since it is an alert sytem it is disturbing.

Has anyone had a similar problem and found the origin and a solution.
This is with stable branch of asterisk and bristuff, starting a few of 
months ago at 1.0.4.


Thanks,

How do you create them?

There is a race condition with asterisk and the spool where if you
create the file or copy it into the queue directory asterisk tries to
read and parse the file before you have finished writing it.  A
suggested method instead is to create it on the same partition then move
it into the appropriate directory to prevent this from occuring.

Create the file somwhere else.  Set the mtime (I think) to sometime in 
the future.  Move the file to /var/spool/asterisk/ourgoing.  Change 
the mtime to the current time or some time in the past.

Always do right. This will gratify some people and astonish the rest.

Thanks, I will try that.

Difficulty is that it happenned only twice in the last couple of months, 
so it will be difficult to know if it is solved or not.

File::copy does copy, it re-writes the file,
you need to move it.
so when the the pointer is placed the file is already there.
