[asterisk-users] Problem when leaving voicemail

[Richard Open Source]

Hi,

I am investigating an issue with voicemail and realtime.

What we are seeing is the following:
1. Caller calls in and goes to an IVR
2. Presses 101 to go to voicemail
3. app_voicemail start and tries to connect to the database trhough
res_config_mysql. However, it takes too long to be able to connect (~15
minutes)
It seems like it first attemots to connect to the database on 16:25:03 and
manage to connect at 16:40:24.

The database and the connection seems to be ok. It is only this query that's
taking long.

We are experiencing this on Asterisk 1.4.17 and 1.4.18 but difficult to
reproduce.

Anybody have any idea what might be the cause and how to procceed and figure
out what's wrong?

Thanks in advance.
