/var/log/ filling up memory's usable log size

[Vexedly]

57m are taken up by letsencrypt's /var/log/nginx

 

This is clearly the problem- spamming up my system log.

nchan: Out of shared memory while allocating channel /cpuload. Increase nchan_max_reserved_memory.

 

I've had trouble with letsencrpt in general. I think my subdomains are no longer working because the log is full. 

I tried to save my system log, but it's taking a very long time to download.

 

Here's a picture of my system log at the moment:

I found this thread, but it seems no one found a solution there.

 

Any help is very appreciated. Thanks!
