Well, we are not shipping UXA enabled by default due exactly to stability issues such as this, however thanks for reporting it, as it helps us in tracking when the UXA stability improves.
Anyway... I see you're using the latest 2.6.3 version of the driver, which is good since we can probably upstream the bug. However, first we need a full backtrace.
