Our phone system does a automatic full backup every night to our server. Recently, the backup could not finish completely causing the phone system to stop running. The only way to bring it back was a reboot. The system appears to run normally but not able to do backups anymore. Any suggestions?
This is part of the error message we are seeing:

Phone System stops
Re: Phone System stops
I would suggest replacing the CF card, make sure it is at least 25X read/write speed. Seems doing a backup every night is excessive, once a week would be fine, possible saved messages should be the only potential loss.
Re: Phone System stops
I'd love to get some more detail from what you see in your event log to see if the symptom may be related to something we're seeing. Can you answer two questions for me:
1. Is the system still pingable when it stops running?
2. Can you expand the filter on the event log after booting it back up to include debug messages, and see if you have a ton of debug messages?
I have a theory that there's a bug in at least v8 where, if too many messages get written to the event log in a very short period of time (a couple of seconds, possibly less), it causes the system to basically die. We've seen two instances of this--the first is some sort of Denial of Service attack generating a ton of SIP Debug events in a very short period of time. The second was an SMTP configuration issue that prevented voicemails from going out for a week. Every few hours the system would try sending everything out again, generating an event log message for each email attempt.
In both of these instances (and we seem to deal with the DoS issue at least once a week), the web admin interface becomes inaccessible, phones lose their registration, but calls that are already in process continue to work and the system is pingable. Only fix is a hard reboot.
