we have gone through every possible plugin and this is the last one. whenever a raidable base gets pasted in the server crashes.

I have raidable bases with copy/paste and have had no issues.   Is this something your hosting or paying a hosting provider?  If your hosting it on your own machine what are the specs of the machine and is it the only thing running?

jvaughan do you have stability enabled? or do you have it set up to allow players to foundation wipe a base? I had to remove the option of allowing players to foundation wipe a base to fix my server freezing all the time. It seems as though Nivex is aware of this and is attempting to fix this in a workaround but as he said "use at your own risk" in his most recent post on another site. To Osiristhevirus, if you have it enabled to foundation wipe, try removing that and see if it helps.
