All items stop working randomly

[arturs]

I run this medium sized tekkit server and lately there have been multiple problems. After I start the server everything goes as usual for about 10min-2h Then all the interactive items stop working - condensers bugg out and you cant take items out of them they just get back in, all engines stop working , solar panels , reactors , powerflowers - Basicly all the blocks that do stuff, even the normal vanilla furnaces.The only way to temporarly fix the issue is to restart. You can still break and place blocks without any problems and store items in chests. The server log does not contain anything unnormal just a bunch of

[buildCraft] Error creating pipe type 0 (class=null)

But I know what that means and its probably the reason for the tps drop. The condensers and everything else can stop working even if the server is at 20tps. Would a map reset clear all those problems?
