Timeouts connecting to DB when running in Linux

Hi,

I have set up a few proget docker containers (web, db), and then started pushing packages to them.

Everything seemed fine, it was running for about 5 hours yesterday.
I come in this morning and the proget web server is down. Logs for the proget web server show:

Logs for the proget postgres container show:

Restarting either/both of the containers did not resolve the issue. Restarting the docker daemon did help, and I saw that about 50k packages had been uploaded.

4h 15m and another 50k packages later I am getting the same problems.

Product: ProGet
Version: 4.7.13

Looks like these symptoms are caused when the host goes OOM
