[asterisk-users] Suden "ast_db_put: Couldn't execute statment" in 13.14.1 after high rate of incoming REGISTERs

[Olivier]

Hello,

The other day, a 13.14.1 server suddenly stopped working correctly.
First, it printed:
Oct 23 21:53:40 FOOBAR asterisk[2377]: WARNING[27942]: db.c:332 in
ast_db_put: Couldn't execute statment: SQL logic error or missing database

This occurred while this server received a lot incoming REGISTER such as:
Oct 23 21:53:40 FOOBAR asterisk[2377]: [Oct 23 21:53:40]
#033[1;33mNOTICE#033[0m[20418]:
#033[1;37mres_pjsip/pjsip_distributor.c#033[0m:#033[1;37m525#033[0m
#033[1;37mlog_failed_request#033[0m: Request 'REGISTER' from '<
sip:johndoe at 100.64.0.1>' failed for '10.50.59.5:5060' (callid:
OA48732DD2johndoe42259F1C) - Failed to authenticate

I estimate incoming (invalid) REGISTER rate to be 120 per second, (which is
by the way, well above the upper limit we load tested our system before
putting it online).

What would you suggest me to do ?

Best regards
