Experiencing Problems with the Game
Experiencing Problems with the Game
I frequently use modded versions of Minecraft, especially the Feed The Beast Monster pack. My server runs locally but tends to crash often. Here’s the crash report you shared: http://pastebin.com/rM2k5sbf
I don’t have access to detailed crash logs or startup behavior. The issue seems linked to an old Java version, so upgrading to Java 7 64-bit might resolve the problem.
That question has been moved to Pastebin: https://pastebin.com/example-link
It fails within 5-10 seconds when launching. I'm using Java SDK 8, specifically the Simply Jetpacks mod version 1.6.4. It functioned properly before my internet dropped around 9:30 and I attempted to start it between 10 and 10:30, but it didn't work afterward. I've tried multiple times since then.
Create a brand new server using the freshly downloaded configuration files. Transfer your world folder to the new server. Only copy the world folder and any whitelist or startup code you have. Always back up before proceeding. Please verify you have the latest Java 64-bit version by checking at https://www.java.com/verify/.
The simply jetpacks mod is being used by many people, not just you. Are you relying on regular server files for the FTB monster content? If yes, that might be the issue. As @Enderman mentioned, updating Java could help resolve it.
I've already attempted that, but I'm ready to try once more. The server is solely for my use, allowing my machines/quarry to operate around the clock. There are no other users on it. I also have the Simply Jetpacks mod in the mods folder within the server.
