11/25/2022, 2:39 AMDear Dominik, welcome to the NeublaGraph community, we archived the forum and switched to Github Discussions(https://github.com/vesoft-inc/nebula/discussions) , sorry for the confusion.
This is a known issue(https://github.com/vesoft-inc/nebula/issues/4205) for old Linux kernel versions

11/28/2022, 1:47 AMDear @Dominik are you still encountering this crash or?
The storage hosts to be activated with
ADD HOSTSd
Dominik
11/28/2022, 2:27 AM127.0.0.1:9779 was what I tried to add as a host I believe. which should be the default I think. I'll add the conf files but I didn't change anything here. storaged error logs are actually empty, metad is always crashing with the above error so nothing else there either. But I noticed that storaged is also very stubborn and stopping it often takes a few 'kill storaged' attempts.
I think I will try to clean everything up and redo the entire setup from step 1 tomorrow.

wey
11/28/2022, 5:50 AMok, then metad crash is the only issue now.
Could you please kindly help report this at https://github.com/vesoft-inc/nebula/issues ?
With reproducing conditions/procedures?
Thanks! This is quite strange/new to us, I am really curious about its trigger conditions.

Dominik
11/29/2022, 5:32 PMwell, I raised an issue https://github.com/vesoft-inc/nebula/issues/4957 but I don't really have any reproducing steps other than install and run as that's all I'm doing, or I don't know what to add.
