Looks like there was possibly something 'interesting' happening with your machine:

"couldn't fork child process: resource temporarily unavailable"

(ie. too many processes, not enough file descriptors available ... )

Are you able to consistently reproduce this?

Looks like there was possibly something 'interesting' happening with your machine:

Unlikely; this only happens with "apr" that I have seen so far. I successfully built GCC 4.3.1 after observing it the first time, and before running "port -d upgrade apr".

Are you able to consistently reproduce this?

Sure. This time with a sledgehammer:

WIthout doing some testing, I can't be sure, but I'm guessing that this is due to the pinging code and is tickled by the longer than usual number of mirror sites for apr.

@dluke: sure looks like it.

@stephen: Can you check if the problem goes away if you use sysctl to increase kern.maxprocperuid? I'm also attaching a patch that should handle the error gracefully if spawning a ping process fails.

catch failure to spawn ping

Changed 5 months ago by stephen@…

Doubling kern.maxprocperuid to 200 did not help.

I'll try the patch later.

Changed 5 months ago by stephen@…

The patch works! DEBUG output of fetch step attached.

I took a look at the output of `sysctl -a', but I didn't see an obvious alternative resource that might be overused. I suppose sockets is most likely.

I wonder if using fping instead of ping might also help.
