Problem with shell

[Atom]

Hi,
I connect to node via ssh, type login and password, but server responds with a huge delay. Shell works with awful freeze or doesn't work at all, while VMs and OpenVZ containers work properly. It's important to note that server respond normally when I try to send some command from remote server via ssh. After reboot server shell works good, but for 24 hours. Then this problem gets back....
I have this problem with server in Proxmox cluster and with standalone server Proxmox VE as well.

Configuration
Proxmox VE 3.4.6, 3.4.8, 3.4.9 (I didn't have this problem with previous Proxmox versions)
HP ProLiant DL380pGen8

any advice?
Thanks

Hi,
sound like an bad nameserver entry in resolv.conf.

If the reverse lookup don't work, the loging wait till dns-timeout.

Thank you

Unfortunately it's not related with dns, because server shell works good during 24 hours after reboot/switching-on. Something happens after a day. I also tried turn off cron, but it doesn't take any effect.
In addition I tried install Debian 7.8 on this hardware and shell works properly
