Hi all,
a bit of a long winded post.
I have been investigating a issue with the USB 3G card and an unacceptable number of link failures. This issue only started after the upgrade to v9, it was not an issue during the v9 beta.
After much experimentation I came to the conclusion that the motherboard was failing.
So a new UTM was required, bought the bits except for the AP10 and the 3G device. Built the box, restored the config and the USB 3G card was found without much effort. Good, the 3G device is working for 2 days without an failure then over the next couple of days the fails rise to 9-10 a day. Restart the UTM and all is well again for a couple of days.
For those that are interested the box is an intel mini ITX server board, i3 dual core, 4gb ram and 120gb ssd and 2 onboard NICs both intel. The users connect to this UTM by AP10 only.
Thought that 9.04-33 might be the issue so rebuilt the box, but didn’t upgrade to 9.04-33. Again it worked fine for about 2 days and slowly the link fails increased. Installed 9.04-33 and the mdw patch. First couple of days after the restart no failures, then the count slowly creeps up.
The UTM logs don’t show anything that is obvious to me. The USB 3G device reports an error back to the interface display. A stop and restart of the interface usually fixes the error for a short while.
Observation, but not always around to check, that after a number of hours when the utm is not used for awhile, then is connected to, the link seems to fail, almost like there is a stack issue which is reset at restart or changes to the USB config?
Other configuration changes I have tried.
1/. changed the fail over testing site, to a site within the ISPs network to see if the failures are caused by 3G network lag, again this worked for a couple of days and then the fail rate increases.
I haven’t tried changing the time out settings on the fail test.
Looking for ideas and suggestions as to what to look for in the logs?
