Hi, this is the info that came with the error message:
panic(cpu 1 caller 0xffffff7f966faad5): userspace watchdog timeout: no successful checkins from com.apple.logd in 120 seconds
service returned not alive with context : unresponsive dispatch queue(s): com.apple.firehose.drain-mem, com.apple.firehose.io-wl
(See attached Additional text.)
iMac 27″, macOS 10.13
"com.apple.firehose.drain-mem, com.apple.firehose.io-wl" typically is related to memory being allocated and released. Although that could be a symptom of something else. This brings attention to your memory, how old is the Mac, did you ever replace or upgrade memory? Can you run the Apple Hardware Test diagnostic to check memory? Other programs like TechTool Pro can also check memory.

My iMac is late 2013, I upgraded the memory to 32 GB.
Thanks for the help. I will run the hardware test at next opportunity.
iMac Randomly Shuts Down. I restarted, then machine restarted itself during process.
