You said this is a VPS, so it's going to depend on which *type* of VPS, but mostly it's a matter of how much memory the VPS is allowed to use, by the host system. It looks like your VPS is limited to 1 GB (989 Mi, it says) of total memory. If your program is coming close to that, then you may need to talk to your VPS provider and get more memory allocated to you (which may cost more money). Try doubling it.

Hi Dan, Yes I've been coding for a living for 15 years in C#. /var/log/messages:Sep 1 12:41:34 debian-s-websites kernel: [31104249.962672] .NET ThreadPool invoked oom-killer: gfp_mask=0x6280ca(GFP_HIGHUSER_MOVABLE|__GFP_ZERO), nodemask=(null), order=0, oom_score_adj=0 /var/log/messages:Sep 1 12:41:34 debian-s-websites kernel: [31104249.973435] oom_kill_process.cold.30+0xb/0x1cf Dan - you found my problem. Thanks! When the program is running I have this: Mem: 989Mi 579Mi64Mi 149Mi 346Mi 120Mi It clearly thinks 64M is not enough. I know my program can require up to a Gig of memory for the bigger datasets. What is the minimum GNU/Linux will tolerate so I don't end up throwing money away on unused RAM?

.Net Core program crashes on Linux and not on Windows
Hi all, I have a program that is meant to run on my Debian VPS which is hosted by Digital Ocean. My access to the server is via Putty. Unfortunately the program simply stops, silently, after a few minutes. My code is littered with try catch statements. The console window shows no errors. It just silently fails. One issue may be that the program is a resource hog working with datasets of a million or so records at a time. Perhaps the system kills processes that threaten to take over all resources? Anyway, I would be grateful for any suggestion on how to track down this problem. I'm happy to read the documentation but as you can probably tell I don't know how to start framing the question.
