After this, is the tripplite_usb process still running? I don't know the default syslog configuration on Solaris anymore, but is there a more detailed system log than what "dmesg" prints? At the LOG_INFO level, the tripplite_usb driver prints out a message if it has given up on reconnecting to the UPS. > This will only happen once in every 50 times or so.

Even when the tripplite_usb driver actually works correctly, it is often attributable to a problem with the UPS :-) All kidding aside, if this does not occur every time, it is going to be somewhat hard to track down. One possibility is to run the driver with some "-D" flags to generate debug output, but this will not work under upsdrvctl - you would simply start the driver by hand, and you will probably want to redirect the debug output to a log file. > It has occurred on different > machines with different UPS’s, so I don’t think it is a hardware issue.

I will admit that I do not have a tripplite_usb driver running continuously, and definitely not a protocol 3003 UPS, so we rely on user reports. -- - Charles Lepple _______________________________________________ Nut-upsdev mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/nut-upsdev
