Alex - Thanks.
I was familiar with the parameters on db_mysql.
So, I understand there is no option for me to fine tune a query timeout etc...
I will have to find a better way to manage my DB related issues.

Hi,
Lately i am experiencing some issues with the sqlops module.
let’s say, for example, that i use sqlops to query some information about the subscriber when an INVITE arrives.
I use kamailio 3.3.2, MySQL 5.6 and the DB server is remote and not local.
Usually, the DB result is very fast and the call continues. But, when the DB is unavailable, or slow, the result is delayed or lost.
In this case:
1. What is the query time out in kamailio?
2. If the database is available but slow, does it mean that no new INVITE will be dealt by the current child process until the sqlops is gone?
3. does anyone has a good idea for managing sqlops in a call?
Thanks,
Uri
