hoping this for my server aliveness check

First: Do you have async save on or off in the config? Did you try both? Secondly you should look what IO Pattern the saving actually takes before assuming latency is an issue at all. Doing an fsync() after a 1GB save file once and adding 1s of latency to that will hardly matter. I have async save ...

I found something interesting. on cloud server, my disk works like this # dd if=/dev/zero of=test1.img bs=1G count=1 oflag=dsync 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 8.65808 s, 124 MB/s # dd if=/dev/zero of=test2.img bs=512 count=1000 oflag=dsync 1000+0 records i...

The train is technically in two-way segment, so it is allowed to turn back. Just remove completely remove signals you have disabled by circuit network to make it one-way segment at it will works as you expect. So is there any debug option to show whether it is one-way or two-way segment? It's usefu...

I constrcuted a dual line railway and using signals to let trains drives only at right side of their direction. bottom-right is a station called station #1 and there's another station at bottom. I have configured this train to moving between home station and #1. home station is collecting coal. And ...

No. I am using vanilla server.

Another desync, occurred when I am on the train and switched to automatic

I am travelling on the train. only me on server.
