[SR-Users] Lost connection to MySQL server during query

[JR Richardson]

Hey Folks,

Getting some annoying logs, pretty certain these are false positives.
I'm running kamailio 4.4.7 using localhost mysql 5.5.60 on debian
7.11. Pretty simple setup, have acc and collecting cdrs. Relevant
kamailio.cfg:

loadmodule "acc.so"
loadmodule "rtimer.so"
loadmodule "sqlops.so"

# -----  acc params -----
modparam("acc", "db_url", DBURLRW)
modparam("acc", "db_flag", 1)
modparam("acc", "db_missed_flag", 2)
modparam("acc", "db_extra",
        "src_user=$fU;src_domain=$fd;src_ip=$si;"
        "dst_ouser=$tU;dst_user=$rU;dst_domain=$rd;"
        "accountcode=$avp(s:acctcode)")
modparam("rtimer", "timer", "name=cdr;interval=300;mode=1;")
modparam("rtimer", "exec", "timer=cdr;route=CDRS")
modparam("sqlops", "sqlcon", "cb=>mysql://rwuser:rwpass@localhost/kamailio")

route[CDRS] {
        sql_query("cb","call kamailio_cdrs()","rb");
}

Logs:
ERROR: db_mysql [km_dbase.c:128]: db_mysql_submit_query(): driver
error on query: Lost connection to MySQL server during query (2013)
ERROR: <core> [db_query.c:181]: db_do_raw_query(): error while submitting query
ERROR: sqlops [sql_api.c:265]: sql_do_query(): cannot do the query
[call kamailio_cdrs()]

CDRs are working fine, no issues with the results, just the log
messages. Errors occur every 5 minutes so this is related to the
rtimer cycle, mode=1 is set for new connection so there really
wouldn't be a lost connection, the old connection should have been
relieved on last cycle.

I've seen some other post talking about this issue but could not find
any resolution or work around. Any help is appreciated.

Thanks.

JR
