Linux dedicated a20 server crashing on RWG

[ssrjazz]

Did a fresh install of a20 on a linux server via steamcmd (I have command line access to this server)

 

At some point during RWG for an 8k map, the server crashes with this in the output log:

While that looks different to mine, you're not using LGSM for this are you? Their server watchdog was seeing that the server wasn't "up" during worldgen and thinking it'd locked up and restarting the server in the middle of the generation process. took me a while to spot it in the logs because things were a bit confused.

No.... but it seems that 8GB of RAM in a server isn't enough to actually be able to RWG an 8k sized map in a20.  I could do a 6k one just fine though.  Guess memory requirements went way up.

If you increase your linux swapfile it should work. I tested on an 8 Gb machine with an 8 Gb swapfile and 8k worked. Most linux installs default to a 2 Gb swapfile, which is too small.
