I had this problem, too, when 'upgrading' from SunOS4 to Solaris2
and found help in the rc-list archive from 1994:

Solaris rshd (and only Solaris) sets SIGCLD to SIG_IGN and
causes wait.c to loop forever waiting for childs. You can fix
this by forcing SIGCHLD to SIG_IGN in signal.c (about line 70):

	if(i==SIGCHLD && h==SIG_IGN)
		h=SIG_DFL;

hope this helps,
