We are seeing what looks like the same problem here, though I have some more details on the aberrant behavior which might help to figure out what is going on. Here is a synopsis:
- environment: happens reproducibly in our demo environment, which is a jetty server running weak single-core VM on an overtaxed machine --- however, similar behavior can be demonstrated on a developer workstation.
- symptom: our client freezes at the "Loading JavaScript, please wait..." --- actually, under the cover, it has just sent the initial POST request to initialize the server (and logged "sending initial handshake to remote bus"), and is sitting around waiting for the response.
- steps to reproduce:
- start the jetty server
- wait until it unpacks the warfile, starts up the server side, and "[bus] buffer status [freebytes: ...]" is logged
- try to connect a client
We can get different, related behaviors after Step 3, however. I've got three interesting cases.
Case 1 - Single client connects to a fast(er) server:
- Client issues intial POST request, and waits.
- Some short time later (e.g. around a minute), server responds.
- Client continues with initialization and runs as expected.
- When subsequent clients (re)connect, the response to the initial POST takes about 100ms.
Case 2 - Single client connects to a slow server:
- Client issue initial POST request, and waits.
- Around 45 seconds later, client logs "components failed to initialize".
- Around 15 minutes later, server emits response to that POST.
- Client logs "received response from initial handshake", continues initialization, but generally hangs waiting for the RpcProxyLoader component.
- BUT, reloading the client page (or any new client connections) after that generally proceed successfully with any big delay after initial POST.
Case 3 - Four clients connect to a slow server:
- Clients issue initial POST requests, and wait.
- Around 45 seconds later, clients log "components failed to initialize".
- Around 25 minutes later, server emits responses to those POSTs.
- Clients log "received response from initial handshake", continue initialization, but generally hang waiting for the RpcProxyLoader component.
- AND, reloading the client page (or any new client connections) after that generally no longer have the big delay after the initial POST, but they fail anyway, showing two instances of "received response from initial handshake" (etc) in the client-side log.
I'll add a client-side log from "Case 3" to the end of this posting. The delay between the client's initial POST and the server's response is corroborated by packet captures on the server VM; i.e., I doubt that the VM networking has anything to do with the problem. I've only tested this with the DefaultBlockingServlet. (We switched away from the JettyContinuationsServlet a few months ago because we were experiencing other strange delays/latency in message handling.) The attached log is from a system using the AsyncDispatcher, although we see the same behavior with the SimpleDispatcher.
Here are my theories about this behavior:
- The server-side does some lengthy/complex initialization *after* it receives the first client request. On a slow machine, this causes it to sit and think for a long time before responding to those first clients.
- If that delay is too long, something(s) timeout on the client-side, and/or server-side --- but other things don't. When the client finally receives a response, the original request handler still tries to handle it, but other components have already given up, so it does not succeed.
- Something is not being locked properly on the server-side, so that if multiple clients connect while the server is still doing its complex initialization, the state gets confused enough that it cannot properly handle future startup of new clients.
If true, 2 and 3 would be bugs of one sort or another. 1 would be an anti-feature --- if that's really what is going on, I think we'd prefer a setting (and/or default behavior) to just do all the initialization at server startup, and not defer anything until the first client request came in.
Here is a grab from the firefox web-console for a client in Case 3 (with some editing/notes):
