From the exception stacktrace, it looks like a failure assembling a rule.
Can you check if you can assemble and compile any other rule, for ex, a function rule?.
I checked our internal systems for error "The test compilation failed without producing a log" and found a hit where the root cause was " Database ran out of inodes. Cleared folder /apps/tmp/PassivationData"
I am not sure of what "inodes" are, May be your system admin could tell if this is relevant here.
