We see more connections to the database since SOGo 2.2.4.

This error says, you lost a connection in mid transport of data and it
can not open a new one.
That is a really generic problem.
Perhaps your network is busy.
Perhaps you run out of port numbers.
Perhaps you have not enough file descriptors.
