Performance problems, Memory Leaks
This chart shows the CPU usage and the memory consumption on the server. The dotted line marks a server restart.
The memory consumption increases over time, which indicated a memory leak and missing garbage collection. Furthermore the CPU spikes to 100% from time to time.
Help is really appreciated to eliminate these problems.
Hi Marlon, maybe thats the rediscache.When the rediscache is starting up, there is a Report that a configuration is missing. I dont know the exact report, and i m on vaccation in the moment.....Maybe you should check this.....Am 01.11.2021 12:05 schrieb Marlon Lückert @.***>:

The Message what i meen is this
WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
The memory usage of Redis is fine:
There are some large objects that are held in memory. But it is really hard to debug that problem.
Yes I think so. But the old server was a fixed price with 32GB RAM included and with Railway it is pay-per-usage, which means I am paying for every single MB of RAM that is currently used. So we can reduce costs with every MB we save.
In front of the railway server is a cloudflare cdn, where I cache the requests. So most of the traffic is actually not hitting the server:
