It starts when i relink my flux energy points to my machinery. But the setup shuld not be so laggy that it would cause the server to crash. Attleast of what i know.
I just want to point out that a lot of times, servers don't crash because of large loads, but because of extraordinary circumstances (i.e. exceptions). Large loads just tend to make the server slow. Do the machines look glitched in any way? Perhaps providing power to them allows them to do something strange? Make sure you minimize cross-mod interactions, because these are often the cause of crashes. Is your wireless flux network contained in as few chunks as possible? A lot of times, mod creators fail to account for chunk deloading, causing a bunch of NPEs to be thrown. If a staff member could post the stacktrace, it would be really helpful right now.
