This is really interesting. pam-ovirt-cred is randomly failing on one of two checks:
https://github.com/oVirt/ovirt-guest-agent/blob/master/pam-ovirt-cred/c red_channel.c#L107 and https://github.com/oVirt/ovirt-guest-agent/blob/master/pam-ovirt-cred/c red_channel.c#L134 Theres no pattern, on which step it will fail. Sometimes it fails on writing to socket sometimes on reading: Jul 18 14:11:02 desktop64 cred-debug: recv() failed Jul 18 14:11:14 desktop64 cred-debug: send() failed Jul 18 14:11:18 desktop64 cred-debug: recv() failed Jul 18 14:11:23 desktop64 cred-debug: recv() failed Jul 18 14:11:28 desktop64 cred-debug: send() failed Jul 18 14:11:33 desktop64 cred-debug: recv() failedOn Mon, 2016-07-18 at 09:51 +0300, Tadas wrote: > After moving to gdm, I've managed to solve the timeout issue.
