Pretty simple, including JEIAddons and trying to connect to my server causes the connection to time out. My console log shows a bunch of null recipe errors.

There's a bunch of PlantMegaPack errors(?) showing up but even without PMP I still time out. I've narrowed it down to JEI, not necessarily JEIAddons. Connects just fine w/o JEI. This started happening seemingly randomly, I didn't change any files between it working and not. The only files I changed at all today was updating RFTools (beta 33). I tried with the previous version of RFTools (32) and the crash still happens.

(Long log, very long. Sorry!)

1. Try connecting with JEI on the server also, I wonder if that is causing an issue?
2. To me, it looks like Plant Mega Pack may be extremely broken for 1.8.9 and all the error logging from JEI is slowing down your client so much that it can't connect. If 1 fails, can you send me a log without PMP on the client and server?

I had been connecting with JEI on the server and same thing would happen.

Yeah, it has like 800 registered recipes for just one type of fruit salad lol, its interesting alright. Here's the log for server+client with JEI and without PMP: https://gist.github.com/gl0x/eb03f26b14d0c8224908

Still timing out :/

unrelatedish- headed to bed, let me know what else I could try tomorrow

Sorry I'm not able to see a problem from the log. Perhaps something on the sever log would help?

Thanks for the report!
Can you paste your client log to http://gist.github.com and link it here?

Here's the server log including when I try to connect: https://gist.github.com/gl0x/01fc2d5c87f2ad07264a

This was with PMP. Again, without PMP and with JEI I still time out. This started happening yesterday after no changes on my side, so maybe my server host has something? I can ask around there if you don't see anything.

To clarify a bit: I was previously able to connect with all of my mods and JEI, now not so much. I'm trying removing mods and seeing if anything helps, maybe Chisel? It adds many blocks. Before, removing flatcoloredblocks would let me connect without timing out.

Hey so removing chisel worked! My not-a-modder guess is that chisel added so many blocks that JEI couldn't get it all figured out in the time MInecraft allows the player to connect?
