InterWorx License Expired Error

From Ubiquity Server Wiki

InterWorx relies on the cron daemon to stay in sync with the license server. If your system is under high load, or cron daemon for one reason or another fails and is not restarted for an extended period of time, you will likely get a message warning that the license has expired or will soon expire. Here's what you'll want to do.

Attempt to manually sync the license
You can do this by executing this command directly from shell

~iworx/cron/license.pex --sync

Make sure crond is running so it continues to sync
Attempt to restart the cron daemon from shell

service crond restart

Make sure your system clock isn't hosed
Run this from shell

service ntpd stop
ntpdate tick.usno.navy.mil (OR ntpdate bitsy.mit.edu)
service ntpd start

The odds of the above fixing the problem are extremely high, but if you continue to have problems, contact Ubiquity support at https://support.ubiquityhosting.com and we'll be glad to help!
