Although that apparently only worked with one backend and not using the
balancer:// URL.

Yeah, although I get that error about the misconfiguration I posted a while
back. I figured out how to get rid of the errors at least, using
ProxyPreserveHost On in Apache to pass the Host: line from the incoming
request gets rid of any errors, however, it still seems to hit some
connection limit. Hopefully that at least helps someone who gets errors
from Errai while backended behind Apache.

Have you tried using the TomcatCometServlet, which using non-blocking I/O?

Some messages go through correctly, like the ones at the beginning.
And if the GET connection times out, it will get a heartbeat json
reply. Although it will usually get one in between with the error
json
below immediately.
Regular messages like subscribing and sending a message manually will
take a while (like 30 seconds or longer) and usually come back with
the error json below as well. Even with one connection it seems to
block
everything else.
I'm going to try more configuration parameters on the Apache side
to
see if it's something on there, but something is definitely
blocking
anything else from going through.
Also, I know we had talked about this before, but will the
conversation messages have a direct callback ability instead of
having
another subject that needs to be listened to? I'm creating an
Errai
Proxy for loading data for GXT stores which in turn is used by
components to get data, but having a secondary subject to listen
doesn't quite fit into the design of this and I think I'd
prefer to
keep it to one method of transport rather than using RPC or SOAFaces
UniversalClient. Not to mention a direct callback seems to fit more
into the conversation design since otherwise data could reach more
than one callback if you had the same component more than once on a
page listening to that reply subject and didn't have an increment
counter
or something to differentiate them.

Interesting. Errai is designed to only use a single connection /
single queue by default with the server in order to prevent
interfering
with image
loading, etc.
We have not tested Errai in any load balancing scenarios such as with
Terracotta.
You're saying all the actual messages are eventually delivered in
both
directions, albeit slowly?
