I just updated our SLES12 SP2 server (with XEN) and after rebooting, it has been very sluggish. I started up YAST to check on the running services and I get the following error message

Internal error. Please report a bug report with logs.
Details: Systemctl command failed: Timeout 30 seconds: LANG=C TERM=dumb COLUMNS=1024 systemctl --no-legend --no-pager --no-
Caller: /usr/share/YaST2/lib/yast2/systemctl.rb:29:in `rescue in execute'

At a loss as to what I should do to address this and get teh server back to normal operations.
