New subject: [Serusers] Voicemail config producing errors and zombies

13 Sep 2004


      I'm using 0.8.14, which I grabbed on 8/6, and sems I got from CVS on 8/25.
Thanks,
Jeff

I saw the "command must begin with..." message before. I think that
error had to do with which release of SEMS you downloaded. Which
version of SER are you using?

Steve,
        I'm trying to use sems and a second instance of ser on 5090.
I did a quick test, and got some new errors in syslog.  I haven't gotten 
far enough to see these before, so I haven't looked into it, but this is 
what I'm seeing:

Again, these are new, so it may be something easy that I'm missing.

What are you doing for voicemail? What app? How are you sending calls to
vm?

Steve,
        I had not.  I put that into the file just now, and I can 
register again.
Thanks for the advice, not sure if vm is working yet, but at least the 
client can connect.

Did you set the set-variable = max_connections=500 in /etc/my.cnf?

All,
    I've been working on voicemail for a while, and haven't made 
much progress.  In looking through the archives I've come up with a 
few example configs.  My latest attempt gives me a number of 
errors.  I was hoping some of the experts could help out with where 
I'm going wrong.  I'm still in a test mode, so there are only 2 
people registering.  When I try to start ser, I get the below 
errors, and a large number of Zombie processes:
Sep 10 15:46:52 enforcer ser[30812]: connect_db(): Too many connections

Any advice as to what I can try would be appreciated.
