/etc/my.cnf (for many years now)
max_allowed_packet = 200M

how can it be that when the whole table file is 54MB large with a setting of 200MB that something is larger then 200MB while obviously it was not too large at insert time at 2016-10-06 but with MariaDB 10.0.x instead 10.1.x?

PHP says mysqli_fetch_assoc() [<a href='http://at.php.net/manual/de/function.mysqli-fetch-assoc.php'>function.mysqli-fetch-assoc.php</a>]: Malformed server packet. Field length pointing 22 bytes after end of packet

MariaDB [afi]> select * from cms1_docmgmt_entrys where doc_id=19;
