Thread-topic: printf logs are not getting printed properly on system.log
Title: RE: printf logs are not getting printed properly on system.log
Hello,
I've encountered this issue too. Specifically, when a lot of calls to printf() have been made, the output looks messy. eg :
printf("foo\n");
printf("bar\n");
Ends up written in system.log as :
fobaro
(just a banal example).
I checked printf() implementation and it seems that loocking *is* handled correctly so I'm really wondering what's the problem behind it.

I've seen the same problem. I assumed it was because of overrunning
some buffer somewhere i.e. producing too much output for the kernel
logging system to cope with.
