Trana-api docker container using a lot of RAM

[yacob841]

I noticed Tranga-api utilizing over 2GB of RAM while most of my other containers range from 20MB-500MB. I thought maybe this was due to it downloading new chapters and once that was done it would slow down but it looks like even when a job isn't running it still is using 2GB. This seems excessive so I was wondering if there was a reason (the reason I am brining this up is since yesterday my system has been crashing every 2 hours and the most likely cause is the RAM getting maxed out and so far this container seems to be the largest contributor)

Can you check how many chromium instances are running?

My server starting slowly crashing again and before it did this time I stopped the Tranga-API container and the system was fine after that. This was not an issue before yesterday and since then it can only last 2-4 hours before crashing. In the meantime I will probably limit the amount of RAM it has access to. This is what I get when Tranga-API first boots up

So its the same old issue with puppeteer not closing chromium-instances, or chromium not closing them when requested...
Will go on another journey to find out how to work around this.

[C9Glax]

Added a separate check in V2 that should periodically close chromium-pages...
