How to actually increase it?
Debug mode again. The server is increasingly unstable. We want to prevent that. We are introducing a debug mode, i.e. a complete recording of everything that goes about the actions of the server before the future crash, finding out the causes and trying to solve them. There are two small problems. The server will slow down significantly and will have a longer start-up. After every fall that happens now, please at least someone tell me what it was and mainly tell me that it fell at all. I'm in another room and I can't keep watching the fall. So when it falls, write to me on my ICQ. I will record crashes, play again, etc. Thank you all for your cooperation and I hope that we will finally get a stable server at least a day online. Debugging is boring, but it has valuable data.

Updates: The server crashed due to one of the spells of the priest and warlock. It has been fixed and the server looks stable. We will return to the server repair solution. Thank you for the quick response about the server crashing and listing all the possible causes that seemed to you at first glance that it may be just what you just did. Let's hope it was for something. Debug server mode in 3 hours took almost 6 GB only in text - debug mode canceled, restarts will now be again in 5 seconds. Thank you for your continued cooperation with such great and smart players as you. Keep it up. Your GM team.
