Description: Watching Server It is the watch dog killing the server. It happens when something is taking to long. With out a profile of what you are doing there isn't much to do, sadly.

is there any way around it?

Without knowing the exact issue not really. Generally speaking these could happen on large crafting tasks, but I've seen them happen before on automated crafting tasks (either using craft on redstone signal or using the crafting upgrade) as those will happen on the main thread.

Closing due to missing profiling report.
