Also, what value do you have for MySQL parameter innodb_buffer_pool_size and how large is your MySQL data directory at peak?

It’ll make your database not ACID compliant, but I don’t see that as being a major issue for transient data such as that stored in the Kamailio DB. I’m not entirely convinced that changing it to a memory table will help as you are presumably doing MySQL replication between your two Kamailio nodes. Memory tables don’t replicate well.

Maximum number of registrations that we can handle with db_mode 3 is 1000 per second.

But when the number of clients goes up writes on the location table become too much and it causes database problems. I even put my location table on a separate SSD disk on the server to separate it's IO but still at times I have problems. How can I move location table into memory? Is this a good solution? What other options do I have? _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org<mailto:sr-users@lists.sip-router.org> http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
