Multiple post-auth queries

Hello, I'm running freeradius 3.0.12 on Debian Stretch amd64 + mysql 5.6 I'm trying to execute multiple queries at post-auth with a configuration like this: query= "statement 1; statement 2; statement 3" With this configuration active I often (not always) get this MySQL error: sql_time: ERROR: rlm_sql_mysql: ERROR 2014 (Commands out of sync; you can't run this command now): HY000 The error does't appear if I just execute two statements. The statements execute insert and updates Thanks in advance Gianluca
