I am trying to make a moded server for me and my friends, and about 1 minute after joining, I have this error:

java.lang.IllegalStateException: Entity is already tracked!

 

I removed all of my mods and error still exist.

I think I found source of the problem. After changing: 

view-distance=7

back to

view-distance=10

in server.properties the bug seem to disappear (25 minutes so far no crash, last time had crash every minute).

Still need more testing, but that may be the reason.

 

edit:

Found real reason. The view-distance only reduced chance of this bug to appear, real reason is in

dormantChunkCacheSize=100

in forgeChunkLoading.cfg

 

I scanned the source and found that this happens only on chunk loading, and it looks like a memory leak, then I tested this value and bingo, without it in my test server(modified so it shows message but not chrash on the bug) had this crash every 5 seconds (with low view-distance).

The reason was entity still kept in buffer/cache and in tracker but still being added again when chunk was reloading (I was running around).

 

Temporaty fix for those with this error is:

dormantChunkCacheSize=0

untill forge will fix chunk buffering.
