What causes the error "Unable to read KLDR_DATA_TABLE_ENTRY" when running .reload?

I see this message in my debugger from time to time while debugging this system I'm bringing up but I'm not sure what causes it nor do I see much when looking through google

kd> .reload /f

Loading Kernel Symbols
Unable to read KLDR_DATA_TABLE_ENTRY at fffff802`05c4d7a0 - Win32 error 0n30

Loading unloaded module list
........Unable to enumerate user-mode unloaded modules, Win32 error 0n30
WARNING: .reload failed, module list may be incomplete

Windows runs fine, I just occasionally hit this and am required to restart them system to get symbols to load correctly. I suspect some sort of memory stomping going but I'm not sure how I would prove that.

Anyone know what causes this error and possible solutions or workarounds for fixing it?
