Server crashes when player loads chunks

[xing216]

Bug Description

We found that when certain chunks are loaded, the server crashes. We tried fixing the cyclic mod problem with adding the language startup parameters, but it still crashes. We do have chunkloaders, but they're not in the same chunk, the same island as the cyclic sprinkler, nor does the game crash when I'm around them.. This is all I can think of and all that I've been able to figure out.

Did this behavior use to work in the previous version?

We did not test this

Steps to Reproduce (for bugs)

1. Player logs in to their island
2. Player walks around loading chunks
3. Server crashes

It looks like there's a huge number of items spilled in the chunks that trigger this crash. This overloads the server and causes it to lag so badly it crashes.

You can probably recover from this by setting max-tick-time=-1 in server.properties - note that this is negative 1 (so that lag doesn't trigger a crash), and then loading the offending chunks and running /kill @e[type=item] in the server console. This may take several minutes to execute. You then need to deal with whatever is causing the item spill, and set the max tick time back to 60000.

This is not really a bug; you can overload a vanilla server in this way too.

I appreciate your reply; However, whenever someone loads in even one of those chunks, it freezes up and seemingly stops accepting commands from the server console. I can execute the command whenever just the chunkloaders are loading in chunks.

Update: We ended up just deleting the entire base and the server still lags out whenever going to those specific chunks. Only one person has gone there as of yet, but I will verify if it's for everyone or not.
