Issue:

Logs end at:

Caused by: io.netty.channel.unix.Errors$NativeIoException: bind(..) failed: Address already in use

Things I've tried:

• Killing all processes associated with neo4j
• searching for default port lsof :11005/6
• reinstalling
  • some config files you don't seem to be able to delete in .config

which OS do you use? use tags for that information

• Linux pop-os 5.4.0-7634-generic #38~1596560323~20.04~7719dbd-Ubuntu SMP Tue Aug 4 19:12:34 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

There was a lot of address already in use going on here, so it was kind of hard to parse, but this bit in the debug log turned out to be the important part:

searched for the port:

$ lsof -i :6362
COMMAND    PID           USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
java    530156 user  427u  IPv6 3670839      0t0  TCP localhost:6362 (LISTEN)
$ kill 530156

Looks like desktop leaves some java runnin' out in the fields there...

After that DB startup was all good.
