Possible infinite loop on mods.eln.misc.Utils.traceRay

[joserobjr]

My server was running fine when suddenly it stopped and all players connection were lost, than the server just stopped there for minutes.

After I restarted, it stopped right after the startup process, I left it running for few minutes but nothing changed, so probably an infinite loop were happening on the server thread.

Then I sent a QUIT signal to the java process (kill -3 PID) to display a thread dump and this is what was hanging the Server thread:

"Server thread" #20 prio=5 os_prio=0 tid=0x00007f8298ec3000 nid=0x29b7 runnable [0x00007f827ca49000]

Hello,
I discovered this problem on my server after placing some blocks (daylight sensor, solar panels) and my server is now frozen 😥.

Can you make a release with this correction ?
