Created attachment 327251 [details] Nut 2.2.2 Tripplite Reconnect Patch Description of problem: NUT tripplite_usb driver segfaults in libc when UPS switches to battery. This causes upsmon to lose connection to UPS driver, think the UPS' battery is immediately dead and begin immediate system shutdown. Syslog trace below: Dec 16 05:25:05 jobs upsmon[2899]: UPS tripplite@jobs on battery Dec 16 05:25:05 jobs wall[27596]: wall: user nut broadcasted 1 lines (31 chars) Dec 16 05:25:07 jobs tripplite_usb[2892]: Error reading B value: Device detached ?
