Hi Paul, sorry for this late answer,

This message means that it took Sympa 1358 seconds to evaluate if the message is allowed to be sent.

Basically, this is the time elapsed while Sympa successively performs the following operations (in this order):

- Display the message "Processing message for <list name> with priority <priority> , <message id>"
- Check message id to prevent loops
- Check that message is not a command faulty addressed to a list
- Check that the message is not a return receipt
- Check that the message is not too large
- If the list config defined topics, check the message tagging
- Check send scenario
- If the scenario allows this message sending, display the log "Message for <list name> from <sender address> accepted (<time elapsed> seconds, <numer of recipients> sessions), size=<message size> "

It's weird that it takes so much time for such simple operations.

Regards,

What does the following line represent?

Feb 20 03:37:30 lists sympa[5631]: Message for ccielab from
address@concealed accepted (1358 seconds, 54 sessions), size=4995

Is it saying it took sympa 1,358 seconds to receive one 4k message?

Paul

Ok, I stopped sympa and moved the msg folder to msg-old and created a new
msg folder. I moved two messages from the old folder into msg and also
posted two messages of my own.

I then restarted the sympa processes. The first message was processed
immediately, but now 20+ minutes later the remaining four are still in
queue.

The only log message is the following:

Feb 20 03:42:44 lists sympa[5907]: Processing message for ccielab with
priority 5, <address@concealed>

Feb 20 03:42:45 lists sympa[5907]: Cannot read
/home/sympa/expl/ccielab/message.footer


I realize there was an error with message.footer, but frankly that has been
the case for the last five years.

Is there any way to put sympa in a debug mode where I can see what is
happening?

Paul

For example, there is a message in /var/spool/sympa/msg that I sent hours
ago. It is just sitting there waiting to be picked up by sympa. In about
a
day or so, sympa will pick it out of the queue and deliver. Sympa is
currently sending messages that were placed in the queue a day ago.

Any suggestions on what I can try?
How many mails are waiting in spool msg ? May be there is a lot of old bad messages in the spool that make "readdir" very long operation. I don't remember how this version deal with spools. I known it is much more better now. Did you check logs ? I doubt that Sympa is waiting without doing anything for hours. Logs will explain the problem.
Also, do you know if I can upgrade directly to the most recent version of
Sympa?
You should but you must check carefully the change log with a special attention to lines related to incompatible changes (they are starting with "****") . One of the major change is that now database is required and parameter data_source in list config file must be set to 'include2'.

Your problem is that automatic upgrade feature is newer then the versioj you are using so it may be a problem when upgrading. Be aware that you must stop sendmail, apache ans all sympa process when upgrading in order to avoid concurrent access to datas that Sympa upgrade process is changing.

Of course for such upgrade, you have to save your database and all Sympa lists environment.
