Hello, Our Primary Mirror control system has a beatnik bsp running on a mvme6100 with RTEMS4.10.2 and EPICS 3.14.12.8 (which understandably is not actively supported). We've experienced a single event that we've never seen before. vmeTsi148 ISR: ERROR: no handler After this it appears all interrupts were disabled and the VME bus communications are down. This system is normally well behaved with uptimes measured in months. In 2020 we had an uptime of 301 days! Has anyone seen an error like this on the beatnik bsp? Subsequent to the error which corresponds closely with a casr command, we see dbScan warnings in our logs. These persisted several times per minute until the system was reboot. Thanks for any insight. -Matt Rippa <8/3/2021 8:00:32 hst>pcs-mk-ioc> casr
