What does MySQL error reading communication packets mean?

What does MySQL error reading communication packets mean?

If mysqld gets its hands on a packet that is too large or corrupted, it assumes something is wrong with the client and closes the connection. If you need large views (for example, when dealing with large BLOB columns), you can increase the query limit by setting the exact max_allowed_packet server variable, which defaults to 1MB.

There are usually no transfers. We had trouble installing solutions because MySQL was getting bad boxes on controller 0. When controller 0 seemed to be removed from the cluster, the build succeeded. Recurring /var/log/containers/mysql/mysqld.log error:

For network problems, use a scheduled round-trip (RTT) ping estimate between the computer that literally hosts mysqld and the computer that the application is requesting from. Send a consistently large file (1 GB or more) to the Turbines client and server, monitor the process with tcpdump, and check immediately if the transfer has occurred.

Suggestions to calm my.cnf-ini in the [mysqld] section – no more than a day and beyond – to keep outdated copies of each used configuration for quick replacement if necessary.

You also have a chance of getting these errors if you are sending a request to someone’s server that is wrong or too wrong. When mysqld receives a packet that is too large or in order, it assumes something went wrong on the client and/or closes the connection.

However, you can assign it to the connection with the error line number. Enable the audit log plugin that logs logins and therefore requests, and check the Percona log audit plugin whenever you encounter a logout error.

How to overcome error reading communication packets in InnoDB?

I did a terrible job looking at some threads on google because following the suggestion I extended this from max_allowed_packet 128 – 512 to 1024 still using the same procedures. I’m using Drupal 7 and yes there are a lot of blobs for datatypes but 1024MB of total max_allowed_packet should be enough according to a few other opinions. Another workaround and overcoming this warning?
