@olivierlambert Right now I am using Node JS version 20 as I saw that XOA uses that version aswell. I thought it might be best to use all dependencies at the versions that XOA uses.
I was having the issue with backup job "interrupted" status on Node JS 24 aswell as documented in this thread.
Actually since I downgraded to Node 20 total system RAM usage seems to have decreased by a fair bit which can be seen by comparing the 2 screenshots that I posted in this thread. On first screenshot I was using Node 24 und second screenshot Node 20.
Despite that the issue re-occurred after a few days of XO running.
I hope that --max-old-space-size Node parameter as suggested by @pilow solves my issue.
I will report back.
Best regards
