RMR version "ric message routing library on SI95 p=4560 mv=3 flg=00 id=a (d5197f5 4.8.0 built: Dec 2 2021"

rmr message sending triggers the routing entry statistics printout every ~5 minutes. When traversing entries for statistics print the mutex lock is missing . So if the routing update happens in same time, then this will cause the crash. Following is the trace (incomplete printout when printing the entry statistics):
