I don't have access to AIX machine, so you need to provide more information.

It may be that, utmp functions behave differently on newer AIXes and start lock, screen by itself doesn't seem to do any locking on /etc/utmp

When I execute Screen sessions I have a lock on /etc/utmp, so I can't execute new Screen and I can't connect root even on console. With lsof I can see the process screen who is locking /etc/utmp and if I kill it, freeze stop.

On AiX 6100-09-07-1614 all is OK

On Aix 6100-09-09-1717 lock on /etc/utmp at the firt screen session

On AiX 7200-01-02-1717 , the lock appears sometime but not everytime, I can't say why, it seems to be random.
