I'm using a QBX appliance, which is just a microATX desktop system with FreePBX connecting to asterisk and some other slapped together stuff running on CentOS 5.4. It's horribly out of date (which I plan to correct really soon).
It has been very reliable until recently. Since Monday morning or so the device has been acting randomly. Sometimes it will just drop all network traffic (web gui/ssh/SIP) and not re-establish itself, but sometimes it will re-establish itself. Other times it will just cut a user off after just over 2 minutes of calling (unsure if coincidental). Other times it will just stop responding to SSH but calls will work.
I suspect the network stack, however nothing in it has changed in weeks. The only thing that has changed was about two weeks ago when I added an extension for a softphone to use. The softphone was used last week before this even started happening, so I don't suspect that. Otherwise nothing has changed, no updates, and I'm the only one working on it.
I can't find anything in the logs just yet, but can someone possibly throw some ideas at me please?
