High Availability error

Just installed HA and after some time I got this error and the active server switched from master to slave.
I had tried to upgrade a module from the GUI, but the GUI froze, so I went to the command line of the active server and did it from there via amportal.
Not sure if that caused the errors, cause some of them were before I attempted the module upgrade.

What happened?
