This was caused by hard disk issues on the license server. The affected window was from 9:06PM - 10:10PM EDT.
If you still have servers fail to start, please do
/usr/local/lsws/bin/lshttpd -r
to get a new license key.
It's also first time happened in years and happened at the worst time - holiday weekend. Our internal team got aware of this first through support tickets, but about 40 minutes delay. We started to investigate the issue around 9:50PM, and fixed at 10:10PM.
We will take actions to avoid this happening in the future. Exceptions caused by any internal server glitches should not affect clients. Exceptions like that shouldn't even be raised, since this has never happened before, so that part of logic has never been triggered .
After the hardware issue resolved, we then continue to check the code of LiteSpeed web server and the code of license validation on the license server. We discussed internally and got an action plan on what logic need to be fixed.
Sorry for late reply to this thread.
Please let us know if you still have issues.
We are terribly sorry for the situation.
