Hello the third time,

just reporting that for some reason Pound just started using the full CPU power on one core:

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM ZEIT+ BEFEHL
 3590 root      20   0 1274244  16664   3144 R  99,3   0,1 37:35.29 pound

it is not a problem for me right now as it is a small private server doing not much else (except sending this email) right now but I don't thing that is how it should be. Anyway I think I'll still keep Pound running (or maybe restart it) for now so if anyone wants to help me with my problem Pound is online and the problem can investigated easier.

Thanks in advance!

Hello again,

just wanted to add that with curl this happens:

emanuel@devuan-emanuel:~$ curl https://nc.emanuel-loos.eu/index.php/login
curl: (92) HTTP/2 stream 0 was not closed cleanly: PROTOCOL_ERROR (err 1)

I left Pound running on my server so as long as there is no crash (like when trying to connect using Firefox or Chromium but not lynx or curl) it should stay online. You are welcome to test it yourself if it helps.

Anyone got an idea what the problem could be or how to debug it further?

Thanks in advance!

However when trying to connect Firefox throws a PR_END_OF_FILE_ERROR and Pound crashes with a storage access error. However when I try to connect using lynx it works perfectly.
