There has been an ongoing issue with the SCS Dragon modem randomly becoming inoperable until rebooted. This is a repetitive issue, and has finally been identified by SCS.
"SCS has identified the source of the problem. The EEPROM cells that carry the log pointers are worn out after > 1 M write cycles. Depending on the traffic load of the modems, that can happen after several months of service. SCS is currently developing a system logging format that no longer needs these EEPROM pointers.
New firmware version 2.30.19 _beta provides a work around and should be used until we release the official 2.30.xx firmware.
If you don’t need system logging at all, you can switch it off permanently using the command (command mode, cmd: prompt): SYS LOG DISABLED 1 and then save that parameter permanently using the SAP command."
