I recently migrated all my logs to a new service, where I could see a recurring bug in mysql.
The message is the following:
Aborted connection <NUM> to db: 'unconnected' user: debian-sys-maint' host: 'localhost' (Got timeout reading communication packets)
Where <NUM>
is some connection id.
I'm not sure if it has to do with a recent change I made, where I migrated my database from mysql to percona server 5.7. My host has Debian 8.7
I don't know what script/cron job is triggered... but all my websites has no problems connecting to same database (all services are hosted in the same VPS).
Any idea? I tried increasing the value of max_allowed_packet, now is 128M but still happening.
