When setting an advanced laser, even without power, the server instantly crashes. The log file shows a tick loop. We had to go to the latest backup which was thankfully right before the advanced laser was set (great timing on auto backup).
We have been getting high ram usage which we thought was due to the host. We backed up, then reset the world, with nothing built, the spawn chunks loaded. Two of us logged on, just loading a few chunks, ram jumped up to 99% usage. The host suggested we try a different modpack. With a different mod pack loaded, ram and cpu usage stayed real low. This is with the Direwolf20 1.0.20 pack.
The host had us install a different jre that is supposed to be better for cpu usage. It did help but it caused the radio to come back with unknown when you turn it on.
We are running Sync 2.2.1 instead of the default
We are also running:
food plus 2.7-PRE
random things 1.8.9 [MC 1.6.4]
I read that the update to Hydraulicraft, as of build 67 the ID's changed so I'm wondering if that will solve it. I will probably try that on a local test server.
I am thinking I should check in creative mode on local server, spawn in an advanced laser, see if server crashes. I realize QuarryPlus has been taken over and continued by a different mod auther. I'll contact them as soon as I have more info.
My main concern is the ram usage with .20 on a new world. I see there is a .21 out now, no changelog on it yet though.
