Hi all,
We catch many coredumps about service instance
operation(ServiceInstanceTable::OnChange) every day!
The following stack is printed with gdb.
From this stack,null pointer access is not found.We have also checked
the log when the coredump happens,none error info were printed then.
Any advice would be appreciated!
The stack
