I have an app that uses a lot of subprocesses, either via NSTask or
via AuthExecuteWithPrivileges. Previously, this data-driven ap would
have maybe a hundred subtasks in a list that were executed when it
was their turn, though some parallelism is possible.
Now, my app just ends doing the subprocesses. No subprocesses are in
the ps list. Apparently, one process has died, but this has not
reached the main app. Given the complex nature of my stuff
(AuthExecuteWithPrivileges talk back through named pipes so I can get
stdout and stderr back separately in a thread in my app)
I am sorry this is all a bit short, but there is no way I can make a
clear and short description of my problem. I suspect I may run out of
some system resource, but I have no idea which one and I suspect some
stuff that normally always works in the frameworks just stops working)
Anyway, I was wondering what the best tools are to track this kind of
a problem down. I have been looking at a few, but haven't seen an
obvious one to help me find out what is happening.
