When I start influxdb I get to following error

I was running fine before, i had to restart the server and now I get this error. The database is not so large:

148M    data
0       replicationq
40M     wal

Its runnning on a WSL2 under Windows 10.

How can I solve this problem?
Thank You

When I start influxd with the paramter --e2e-testing it is runnning.
Dashboards and tasks are there, but it seems no data.

I am running Version 2.6.1

An update to 2.7.0 did not help

Hello @Tesla2k,
Hmm that is odd.
I wonder if it’s related to needing to correct the ulimit?
I have this in my ~/.bash_profile to make the limit huge:
ulimit -n 10000

I tried ulimit, but it did not help. I ended up with deleting /var/lib/engine and reimported my data…
