I rather not involve any additional 3rd party software. Would my work-around work, setting the ping_interval to a higher value than the wait_timeout? My expectations of that would be that MySQL would kill off the idle connections before Kamailio attempts to refresh it. I could set the ping_interval to 28800 or something like that.

You can use a local ProxySQL for connection pooling. ср, 11 февр. 2026 г. в 16:43, Martin Nyström via sr-users <[email protected]<mailto:[email protected]>>: Hi, Is there a way to control the number of database connections kamailio opens using the db_mysql module? We only use the database connection when the service is started, and random XML-RPC reloads, so we have no need of having 10+ open database connections around the clock. Would a work-around be to set the ping_interval to a higher number than the mysql wait_timeout? Are there any implications of this? If there is no connection available I expect Kamailio to open one when needed. /M __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions -- [email protected]<mailto:[email protected]> To unsubscribe send an email to [email protected]<mailto:[email protected]> Important: keep the mailing list in the recipients, do not reply only to the sender! -- BR, Denys Pozniak
