I never never never had this kind of problem with Wordpress, but starting from latest releases – I don't know when –, I have this problem:
«The redis service of the app at xxx ran out of memory».
Of course, I increased memory from 150 to 256 Mb. But after few days, again: «The redis service of the app at xxx ran out of memory». So, I increased again to 512 Mb... and again «The redis service of the app at ran out of memory».
I think there is something is not working properly, but I don't have the necessary skills to be able to investigate.
Anyone had a similar problem?
Thank's a lot, take care
Edit: Opening to Url with post ID, gave this problem. I had to "Flush" Redis cache:
Edit2: I increased Redis memory to 1024 Mb.
Not exactly the same issue, but I've noticed since updating to 7.5 that quite a few apps seems to suddenly be running out of memory despite the fact they never ran out of memory before and have the exact same memory allocated as they did before.
Earlier an instance of Umami ran out of RAM, but the graphs show it going up to 400MB at that time whereas it has 2GB allocated. Seems odd. Have noticed similar strange stuff with other apps too.
