Hi All , Is there any update on this ?
Just to elaborate the error a bit , I have opensips running on eks cluster nodes and multiple opensips nodes used to connect to the same RDS (Aurora mysql). On the RDS side there was a minor version upgrade from 8.0.mysql_aurora.3.07 to 8.0.mysql_aurora.3.08.2 . After upgrade when register request comes to opensips and it goes to insert the data in the DB. It gives the above error which I shared earlier . *CRITICAL:db_mysql:wrapper_single_mysql_stmt_execute: driver error (1243): Unknown prepared statement handler (5) given to mysql_stmt_precheck* *ERROR:usrloc:db_insert_ucontact: inserting contact in db failed","attributes* *ERROR:usrloc:wb_timer: inserting contact into database failed* *As for my understanding : * During the Aurora mysql upgrade from 3.07 to 3.08.2 1. All old DB sessions are terminated and reset . 2. The Auro engine restarts and resets all session level state . 3. However opensips SB driver (db_mysql) still holds references to old prepared statement in an old connection pool . 4. When the connection is reused by opensips after upgrade , those handels does not exists anymore and hence → driver Error 1243 appears in opensips logs (invalid prepared statement and failed to insert data in the database ) . 5. Once we restarted the pods the connection pool from opensips side also got reset and hence the issue got resolved . *But restart is not suitable for live environment . So is there any other option to recover this automatically . On opensips module documentation for db_mysql * *I am not getting any such parameter to set . Do I need to update the mysql client version to ? Please suggest . * *Thanks & Regards* *Sasmita Panda* *Senior Network Testing and Software Engineer* *3CLogic , ph:07827611765* On Tue, Oct 21, 2025 at 11:14 AM Sasmita Panda <[email protected]> wrote: > Hi All , > > I am using opensips 3.4 running on EKS node and the database is AWS RDS ( > 8.0.mysql_aurora.3.08.2) . > > In the config I am using sql_only mode to save/extract data from the > database . > > loadmodule "usrloc.so" > modparam("usrloc", "nat_bflag", "NAT") > modparam("usrloc", "working_mode_preset", "sql-only") > modparam("usrloc", "db_url", "mysql://mysql-user:mysql-pass@mysql-domain > /dbname") > modparam("usrloc", "use_domain", 1) > modparam("usrloc", "max_contact_delete", 1) > > if ($rm=="REGISTER") { > xlog( "L_NOTICE", "Register Contact & $ct \n" ); > fix_nated_register(); > > if(!save("location","force-registration,max-contacts=10,path-lazy")) > sl_reply_error(); > exit; > } > > > Below is the error I am getting in the opensips logs : > > 2025-10-20 00:30:03.120 > {"body":"Oct 19 19:00:03 [36] NOTICE:Register Contact \u0026 > \u003csip:[email protected]:57670 > ;transport=wss\u003e;expires=90","attributes":{"log.file.path":"/var/log/pods/eks-opensips_west-registrar-f5c5896d4-rgn8d_44da0dac-0521-4e1b-b4e7-89c7f0f87c11/west-registrar/0.log","log.iostream":"stderr","logtag":"F"},"resources":{"k8s.container.restart_count":"0","k8s.pod.uid":"44da0dac-0521-4e1b-b4e7-89c7f0f87c11"}} > 2025-10-20 00:30:03.121 > {"body":"Oct 19 19:00:03 [36]* > CRITICAL:db_mysql:wrapper_single_mysql_stmt_execute: driver error (1243): > Unknown prepared statement handler (5) given to > mysql_stmt_precheck","attributes* > ":{"log.file.path":"/var/log/pods/eks-opensips_west-registrar-f5c5896d4-rgn8d_44da0dac-0521-4e1b-b4e7-89c7f0f87c11/west-registrar/0.log","log.iostream":"stderr","logtag":"F"},"resources":{"k8s.container.restart_count":"0","k8s.pod.uid":"44da0dac-0521-4e1b-b4e7-89c7f0f87c11"}} > 2025-10-20 00:30:03.121 > {"body":"Oct 19 19:00:03 [36]* ERROR:usrloc:db_insert_ucontact: inserting > contact in db failed","attributes":* > {"log.file.path":"/var/log/pods/eks-opensips_west-registrar-f5c5896d4-rgn8d_44da0dac-0521-4e1b-b4e7-89c7f0f87c11/west-registrar/0.log","log.iostream":"stderr","logtag":"F"},"resources":{"k8s.container.restart_count":"0","k8s.pod.uid":"44da0dac-0521-4e1b-b4e7-89c7f0f87c11"}} > 2025-10-20 00:30:03.121 > {"body":"Oct 19 19:00:03 [36]* ERROR:usrloc:wb_timer: inserting contact > into database failed* > ","attributes":{"log.file.path":"/var/log/pods/eks-opensips_west-registrar-f5c5896d4-rgn8d_44da0dac-0521-4e1b-b4e7-89c7f0f87c11/west-registrar/0.log","log.iostream":"stderr","logtag":"F"},"resources":{"k8s.container.restart_count":"0","k8s.pod.uid":"44da0dac-0521-4e1b-b4e7-89c7f0f87c11"}} > > *** I have 2 instance on which opensips running and the Database is common > for both . > > *Thanks & Regards* > *Sasmita Panda* > *Senior Network Testing and Software Engineer* > *3CLogic , ph:07827611765* >
