"There is a broken chunk your best bet would propably be to save your important chunks with mcaselector and remove every other chunk."
True, after all i managed to save the server, i saved the first files inside region, i just left the good files in it (Deleting the ones that made the server crash).
I made many tests to leave much files of r.x.x.mca as i can.
Thank you for the support!
First of all, i would like to explain you that i use the mod Pixelmon Generations.
So i play with 2 more friends on a private server that we created, we played a lot on this map (Big Area Discovered, catch a lot of pokémons, have a lot of mega evo) the map has more than 200 MB.
Unfortunately, today we tried to recconect and my friend realized that the server started to crash as one of us connected to the server, so i took the lead trying to solve the problem using the Techinc Launcher and the TL Launcher with the Pixelmon Generations but the problem keep happening.
I managed to get the Log: https://mclo.gs/VTUOI1e , i hope that someone can help me with this one!
I have tried to use MC Edit to erase some part of the map but i got error when the program tries to open so i hope that you help me out with the log problem. 
Thank you for your support!
