Assertion failed in src/rem.c line 1371

Question

SDK: 10.0.0 
 Softdevice: s110_nrf51_8.0.0 
 
 I'm working on migrating our application from SDK v9 to v10. I'm getting a softdevice assertion failure in src/rem.c line 1371 reproducably at a certain point during the application's startup. Could I have some details on what causes this particular assertion so I can debug further? 
 Thanks, 
 Mike

It turned out we had inadvertently set SPI interrupts to priority 0, so we were causing the softdevice to miss its timing constaints when there was a lot of SPI traffic. We've set that back to low priority and are no longer getting any failed assertions. 
 Thanks for the help, 
 Mike
