Hi
I had a similar issue with my enfora modems. I fixed it with a modem
firmware update. You might want to contact modem manufacturer and
report the issue.
Somehow modem lost message memory locations thus unable to find
messages. this finally hung the modem and a reset is needed to have it
back online.
Regards
