Once in a while my application is blocking somewhere in the kernel:
# Report 0 - Time Profile of Tigger.mshark - Time Profile of Tigger
SharkProfileViewer
# Generated from the visible portion of the outline view
+ 100.0% ml_set_interrupts_enabled (mach_kernel)
| + 80.0% run_queue_remove (mach_kernel)
| | + 80.0% thread_block_reason (mach_kernel)
| | | + 80.0% uio_duplicate (mach_kernel)
| | | | + 80.0% selprocess (mach_kernel)
| | | | | + 80.0% select (mach_kernel)
| | | | | | + 80.0% unix_syscall (mach_kernel)
| | | | | | | 80.0% shandler (mach_kernel)
| + 20.0% wait_queue_assert_wait (mach_kernel)
| | + 20.0% selprocess (mach_kernel)
| | | + 20.0% select (mach_kernel)
| | | | + 20.0% unix_syscall (mach_kernel)
| | | | | 20.0% shandler (mach_kernel)
Any idea what the reason could be or how I could find out?
Should I rather ask in darwin-dev?
Thanks for any insight.
Andreas
