In Confluence Administration, (Menu : Administration -> Support Tools - Instant Health)
I saw the message
'Max Allowed Packet'
-> checks if the max_allowed_packet variable in your MySQL database is appropriate.
-> change max_allowed_packet variable to 34M
So I changed the max_allowed_packet variable 16M to 32M as maria DB
recommendation (two times 16M).
Is it a must to change the max_allowed_packet variable size to 34M?
If it is difficult to change, what is the result?
Unfortunately, in my experience I have set different values for mysql, percona - different values not multiple of 2.
And in documentation in Maria DB, I have not seen any info about multiple of 2.
For my instance have set max_allowed_packet = 256M
Because it is need for faster backup.
Hence you can set 64M, for to be in deal with your system administrator:)
