Apple LLVM compiler 3.1 error - iOS 5; Xcode 4.3

Question

I have been receiving this error for a long time and I don't know what to do.

In order to keep the question short, I have written the error into a .rtf file and put it into CloudApp. Here's the link: http://cl.ly/0T3n1Q123u352T372t0m

I think it has something to do with "CLAPIDeserializer.m".

I will appreciate any help. Thank you.

Answer 1

When this happens, close xcode and issue the "purge" command in Terminal then restart xcode. That solved this error for me.

Answer 2

It means your OS X kernel cannot spawn any more processes for your user ID. There is a maximum number of processes per user:

To see your process limitation:

sysctl kern.maxprocperuid

To check how many processes you have running:

ps aux | grep username | wc -l

To see how many zombie process:

ps -v -u username | grep -v grep | awk '{print $2}' | grep Z | wc -l

To see what they are:

for pid in `ps -v -u username | grep -v grep | awk '{print $1, $2}' | grep Z  | awk '{print $1}'`
do
  ps -o command="" -p $pid >> zombies.txt
done

None of these processes can be killed, and purge won't work on my mac, 10.8.2.

You could temporarily increase the max user processes count:

sudo sysctl -w kern.maxprocperuid=1024

Then in your .bash_profile or .bashrc add:

ulimit -u 1024

And change Finder’s limits:

sudo launchctl limit maxproc 1024

But really, it's time for coffee and give your mac a reboot..
