This morning when launching my OS X application in XCode it it logs two strange messages that I haven't seen before:
2018-07-29 12:11:57.265197-0600 appname[1642:302161] flock failed to lock maps file: errno = 35
2018-07-29 12:11:57.265620-0600 appname[1642:302161] flock failed to lock maps file: errno = 35
In the header file sys/errno.h this is defined as:
/* non-blocking and interrupt i/o */
#define EAGAIN 35 /* Resource temporarily unavailable */
This isn't a fatal error, the app runs normally after this. The project appears to log this before the multiple doc appplication loads its first doc window. I don't think I changed anything since yesterday when this wasn't happening.
What does this mean and how can I fix it?
