2143808 - TIME_OUT shortdump raised by program SAPLSENA when copying existing user at transaction SU01

While you try to copy an existing user into a new one at transaction SU01, the operation will keep on processing like if it was hanging. In transaction SM50 (work process table) you can see a RUNNING work process executing program SAPLSENA (lock handling) but the runtime only increases and most of the times it will raise a TIME_OUT short dump.
