Hi all, I just installed kamailio 5.2.4 on two separate aws instances in two separate regions. Both regions uses the same configuration template and share the same db in AWS RDS. The issue I see is this: - SJO location was able to launch fine without any issues. - ASH location could not start up kamailio process due to db connection failure:
Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8043]: ERROR: db_mysql [km_my_con.c:139]: db_mysql_new_connection(): driver error: Too many connections
Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8043]: ERROR: <core> [db.c:319]: db_do_init2(): could not add connection to the pool

Sep 10 21:24:13 ashmainkama51 /usr/sbin/kamailio[8045]: ERROR: <core> [core/sr_module.c:847]: init_mod_child(): error while initializing module carrierroute (/usr/lib/x86_64-linux-gnu/kamailio/modules/carrierroute.so) (idx: 30 rank: 18 desc: [tcp receiver (generic) child=9])
- In ASH instance, I can manually mysql to the RDS host using the credentials in the config file. - I checked db user permissions and it's opened for the subnet in our ASH location (which is also proven using manual connection).
So I don't get why one works and the other doesn't
Thoughts?
