supernode doesn't reconnect? #41

Closed keo closed 10 years ago

keo commented 10 years ago

I started hacking on the BoP server.

I installed it on OS X 10.8 and was able to successfully run it (thanks a lot Tamas for the help).

It started downloading the blockchain, but after sending my computer to sleep, then waking it up I realized the the server doesn't reconnect.

I tried reproducing the error: turned WiFi off, waited 5 minutes, then turned it back on, then started watching the data dir, but it didn't continue to grow.

Here's the output from the console:

Is this a known issue or am I doing something wrong?

I would love to fix this and create a pull request, but I'm not a java guy unfortunately.

UPDATE:

I left my computer open for this night for the blockchain to download. Today morning I checked it and it downloaded a considerable amount, but then stopped again (this time it was open, with network available).

It can be seen that as some peers go down, others come up, etc. - which is good. Then suddenly it says "P2P Peer connector Could not discover peers" and all peers disconnect.

I am using the top of the master branch.

The disconnects look like if they would have been timed out after long inactivity, then the "Could not discover peers" indicates that it did not get new hints from DNS seed. I guess this is some networking problem or operating system limit (sockets) exhausted. The initial chain download is quite greedy and wasteful with resources. Try restarting it. Switch on higher log level and rebuild if the problem persists to get more insight. Log level is in server/src/main/resources/log4j.properties

Thanks for the reply.

Restarting helped it. Also starting it as a slave with an existing, already downloaded blockchain through bitcoind made it a lot faster to catch up.

This doesn't slow the network problem. Here's how to reproduce it:

  1. Start a fresh new server, wait 2 minutes
  2. Turn WiFi off (or unplug the cable), wait 5 minutes
  3. Turn WiFi back on
  4. The server can't get back online. Wait for another hour while fully online, but it still doesn't find its way back.

This is probably a bug.
