ERROR: mx_mysql_stmt_prepare: Lost connection to MySQL server during query

[pmenzel]

Two days ago, mxqd terminated on wombat:

$ pgrep mxq
$ echo $?
1
$ tail -4 /var/log/mxqd_log
2024-02-13 18:06:21 +0100 mxqd[10447]: Main loop started 125 slots.
2024-02-13 20:17:32 +0100 mxqd[10447]: ERROR: mx_mysql_stmt_prepare: Lost connection to MySQL server during query

mxqd: mx_mysql.c:1158: mx_mysql_statement_close: Assertion `*stmt' failed.

Ah, that's already fixed in my next branch by "mx_mysql: mx_mysql_statement_close*: Allow NULL".
