Comment-Added:
Actually, there is a problem in the pthread mutex code in
recent levels of Apache 1.3 which can result in this situation (not being able to kill idle children).  I've only seen it occur on AIX but the problem is in the generic Apache code for pthread mutex handling, not in any AIX-specific area.  I don't believe that anybody is working on a fix for this.

If it is a problem that idle children aren't being terminated, the work-around is to switch to fcntl serialization.  There are two ways to do this:

1) upgrade to the latest Apache 1.3 and put "acceptmutex fcntl" in your config file
2) for older Apache 1.3 on AIX, edit src/Configure, find the appropriate AIX stanza for your version, and remove "-DUSE_PTHREAD_SERIALIZED_ACCEPT" from CFLAGS and rebuild
