Yes! We experienced the same thing on several Windows servers we had running 188.8.131.52 RC. Tomcat appeared to hang, slowing the servers to a crawl -- and we struggled just trying to stop Lucee.
Ultimately, we had to reboot every server, just to get control of the situation.Downgrading to Lucee 184.108.40.206 solved the problem for us - at least so far.
It's been about 30 hours since the downgrades, and all is working fine.
