[CRASH]Server fails to restart, server crashes/hangs, random high pings

[FoxWyvern]

This is probably not an Essentials problem but I'd at least like to open it as a topic of discussion so that more can be learned about the issue. I'm going to attempt to post this as a bug on Keen's forum as well as I do believe this is more of an issue with the new version of space engineers although I'm posting it here in case it has something to do with SESE having not had an update for the newest version of SE.

I've noticed the following issues since the last Space Engineers update

-Server crashes roughly every other day.
-Random players get extremely high ping but doesn't affect anyone else connected to the server at the same time.
-Server does not automatically restart. (Essentials feature)

Server Currently Using:
Space Engineers: 01.089.014
SESE: 1.88.11.543
Essentials: 1.13.2.2443

Not using:
wvm, wrr, voxel concealment, or GetOutOfMySandbox

I am not noticing anything of any value in any of the logs, which I'll post below. When the server crashes, the server initiates a shut down and unloads the essentials plugin (which is probably why the server does not automatically restart). It then hangs and still allows incoming connections but anyone who trys to connect will get stuck at the "Downloading World" screen.

My server is setup as an instance and has restart in the target line with the timed restart and unresponsive restart enabled for essentials. However, the actual service for the instance has been set to manual instead of automatic which I do not believe is an issue in this case but mentioning it just in case.

All crashes to my knowledge have occurred when a player is mining, although one player said he "was about to start mining." However, none of the other server admins I spoke to have noticed any abnormal behavior with their own servers.

Additionally, random players at random times are experiencing excessively high pings, in the 10s or even 100s or thousands high before dropping back down to high 1,000s and randomly jumping up and down till that player reconnects. These ping spikes appear to happen randomly and to random players and do not affect other players who happen to be on the server at the same time.

None of these issues appear to be able to be repeatable on demand so easily identifying a script or plugin that may or may not be causing this is extremely difficult. However, both problems have appeared to crop up at the same time.

Note: Problem getting entities, skipping update seems to be a common error flood when the server UPS drops dramatically due to players mining.

Is it a creative server ?
