Sleep-Wake Failure
My iMac running OS High Sierra has for last several days experienced a sleep-wake failure. The diagnostic report has a repeating section as follows:
Thread 0x3ec8cd Thread name "thread call kernel-high #3" 8 samples (1-8) priority 92 (base 92)
<IO tier 0>

*8 machine_switch_context + 205 (kernel + 1580685) [0xffffff8000381e8d] 1-8
Can anyone help me figure out what's causing this and tell me what I can do to correct it?
Thanks
