[snip]This appears to all be triggered by an ssh into localhost (I have two accounts on this machine and sometimes have to swap and ssh is easiest to forward display and not have to enter password):
$ ssh -vvv XXX@localhost
...
debug1: Entering interactive session.
debug1: pledge: networkAnd here it hangs for ~30s then proceeds ok but then within the next few minutes X will crash due to systemd crashing.
This also happens if I ssh into a different machine on the network.
This only happens for a NIS user.
Not for local accounts and I’m guessing this line from the journalctl above is the root cause:
Oct 13 16:20:58 jop85 systemd-logind[369]: do_ypcall: clnt_call: RPC: Unable to send; errno = Operation not permittedI am at a loss even where to continue from here so any advice is appreciated!
Again this all worked fine a few days ago.
Thanks!
Jay

Solved, anyone else running into this see here for more information:
https://www.bountysource.com/issues/502 … d-suchlike
Suggested solution is installing nscd (caching nis locally).
But I went with commenting out IPAddressDeny=any in /usr/lib/systemd/system/systemd-logind.service
