Package: razor
Version: 1:2.85-1
Since a few days razor repeatedly reports "Couldn't parse server greeting",
albeit surely not on every received message. All in all, things seem pretty
similar as reported at [1] 2 years ago. I tried to reproduce this on the command
line and in one of many tries I noticed:

Most likely this is just caused by server overload, but why not make the code
retry, say, 3 times if $greeting is undefined!?
Thanks a lot,

I don't think this would be a good idea. If the servers are overloaded,
making clients to retry 3 times would make them to be even more overloaded.
Also, if the servers are overloaded right now, the probability that they
remain overloaded in the next seconds will be very high as well.
(Sorry for the late reply, I've just adopted razor today).
Thanks.
