You probably just have not enough RAM allocated for the amount of mods on your server or something. BlueMap runs with very little available heap-memory..

Also you said you are using the forge version of bluemap, but your logs suggest that you are running spigot? Note that hybrid-servers are not supported by bluemap.

If you still believe this is a BlueMap bug, please provide a HeapDump for me to analyze (-XX:+HeapDumpOnOutOfMemoryError).

If you need support, please use our discord :) I will close this Issue and reopen it in case you provide a HeapDump.
