Hello,

    I am very very very frequently seeing in logs "Lost connection to MySQL Server" --- the MySQL server that it is connecting to is less than 1 ms away (essentially sitting in the same rack).

Dec  8 19:21:15  /usr/local/sbin/kamailio[4149]: INFO: dialog [dlg_db_handler.c:584]: trying to remove dialog [c9d5ed0-13c4-4ee10778-92e3eb21-a90244c@XXX.XXX.XXX.XXX], update_flag is 4

Dec  8 19:21:16  /usr/local/sbin/kamailio[4149]: ERROR: dialog [dlg_db_handler.c:598]: failed to delete database information

*** MOD PARAM CONFIG ***

# database ping
modparam("db_mysql", "ping_interval", 150) 
modparam("db_mysql", "auto_reconnect", 1)

Any thoughts on what may be happening?  It seems the overall connection (network) between the two servers is great.

Thanks for your time & input in advance!

Sincerely,
Brandon Armstead
