That is fine. Seems like the server is flooded pretty much and there is
not enough resources to process outgoing messages even on small
blocking delays.

My recommendation is to decrease s2s/c2s shapers as much as possible,
clean the server from malicious accounts and restrict the registration.
I really don't think you can do much here, alas :(
