When a player is not in a world (sitting on the main menu), the bot constantly disconnects and reconnects every 10-30 seconds, spamming the IRC chat with connect/disconnect messages.

Version: 1.7.10-2.9.396
Forge: 10.13.4.1614 (1.7.10)

Here's what is happening in the IRC chat: https://hasteb.in/asurafegiy.txt

If you need more information, please let me know.

Is there anything in the Minecraft client log related to the reconnects? I've tried to reproduce it, but it stays connected for me.

I found this in the log:

[07:28:13] [IRC (irc.spi.gt)/INFO]: [CHAT] EiraIRC encountered an unexpected error! The connection to irc.spi.gt was closed.

I have a sneaking suspicion that the disconnects are due to the mod not responding to the server when it receives a PING since when it reconnects the server says:

[07:28:29] [IRC (irc.spi.gt)/INFO]: [CHAT] [(elmer.spi.gt)] *** If you are having problems connecting due to ping timeouts, please type /quote PONG n]iMcGqmJ or /raw PONG n]iMcGqmJ no

It's an intentional disconnect, ping timeouts would result in a different quit message.
It seems something is crashing the connection - the important part of the log (the stacktrace) should be right below in the log of what you've posted.

This is all I see in the log repeating over and over.

[07:27:55] [IRC (irc.spi.gt)/INFO]: [CHAT] EiraIRC encountered an unexpected error! The connection to irc.spi.gt was closed.

[07:27:55] [IRC (irc.spi.gt)/INFO]: [CHAT] See the log file for more details.

Okay. Can you try running this build? I made it crash properly instead of just complaining in the log, so we should be able to see what's causing it then.

Thanks, you may just turn out to be the saviour of esper.net.

Loading up the client now, just waiting for all 120 mods to load up =P

Okay, after some time I myself got the mod to crash. here's the stacktrace:

Awesome. This has been an issue for so long and we could never figure out why the continous reconnects happen. I've learnt my lesson: making things only error and not crash when it really is a crash is a bad idea because no one will ever report it. Fixed builds are on Jenkins or will be up on CurseForge in a bit.

I'll be sure to update, and hopefully the one hour ban I earned from it was worth it xD

Long story short... I was on the Spigot IRC server and was in the main channel when all of errors occurred. One of the half-ops banned me for an hour and messaged my main account letting me know what had happened. At least he understood that it wasn't me doing it on purpose.

Haha, sorry about the temp-ban, but yes, it was absolutely worth it. :)

It's fine, and I do agree with you, it was well worth it xD
