Calling malloc_create_zone followed by malloc_zone_register of said zone is causing the problem. Omitting the register seems to work fine and doesn't cause the hang. Is this legit? Are you not supposed to register a zone after creation? The comments in malloc/malloc.h say that malloc_zone_register "regisers a freshly created zone; should typically be called after a zone has been created". Or this function only for zones you're building from scratch (i.e., filling out the structs)? >From Google [I haven't bothered to actually download the darwin- source for malloc to make sure], but malloc_create_zone() calls malloc_zone_register() on the zone before returning. Given the lack of documentation, I would postulate that you should only call malloc_zone_register() for a zone that you somehow create yourself, without the use of malloc_create_zone().

You could as Dave or file a bug. But see above; there are legitimate reasons for persistently retrying. Probably they outweighed the likelihood of an actually broken plists remaining installed or exporting a service legitimately required by some other process and the system remaining functional. -- Terry _______________________________________________ Do not post admin requests to the list.

If option 'KeepAlive' is more powerful than the old 'OnDemand' from Tiger, why there isn't an (sub)option, something like 'MaxRetries', to control the number of successive failures before launchd aborts the task? 2. Why this new comportment to retry infinitely is not documented? I guess you missed the part where I said you could ask Dave or file a bug. This email sent to site_archiver(a)lists.apple.com
