Problem DW20 1.10.2 server hangs if idle, login requests time out

I'm currently hosting a DW20 1.10.2 server for myself and friends and about a week ago people started timing out when trying to connect. The server log would show nothing aside from the connection attempt, but would also hang until I restart the server. Now I have to restart the server for anyone to log in. As long as there are players already logged in, nobody has any trouble. The server has plenty of memory, but only uses around 1.5gb. I've used this box to host previous FTB packs without issue. Does anyone have any thoughts on why this is happening? Thanks in advance!

If I log into my server from the same network after it's been idle for a 15 minutes, I see this (attached) and it never finishes loading in the surrounding chunks or allows me to interact with the world. After rebooting, I can play forever until I log out and it goes idle again. What could be causing this?

I am having this same issue, but on FTB Infinity Lite 1.10.2 1.5.1
I seen it on prior versions as well, but with the update to 1.5.1 it is actually writing out a bug report, which I have attached.

After the crash the server console says the following:
[16:01:28] [Server Watchdog/FATAL]: A single server tick took 60.00 seconds (should be max 0.05)
[16:01:28] [Server Watchdog/FATAL]: Considering it to be crashed, server will forcibly shutdown.
[16:01:29] [Server Watchdog/ERROR]: This crash report has been saved to: D:\InfinLite\.\crash-reports\crash-2017-01-13_16.01.29-server.txt
[16:01:29] [Server Shutdown Thread/INFO]: Stopping server> Exiting...

If you change this in server.properties to -1, your server will not crash but will hang indefinitely
max-tick-time=60000

Just curious if anyone has come across this issue or a solution yet. My world is still having this issue - if everyone logs out, after about 15 minutes it timeouts and prevents players from logging back in. If someone stays logged in, the server never has an issue.

Can you share the server log from a time that this happens?

/logs/fml-server-latest.log

Copy the contents of that file and paste to paste.feed-the-beast.com and share the link to the paste here.
