Applications Loading
« on: October 02, 2015, 08:15:21 PM »
When a phone goes resilient, it says "Applications loading".
Then when it fails back it does the same thing.
Any idea what is loading here?   It takes a very long time to get every phone loaded.

I'm thinking there is some form that isn't shared but I'm not sure what it is.

I can't offer any help, but only say that we've seen the same Applications Loading taking forever for several months now.

Hi Ralph

which version software are you running on the 3300?
This can be a software bug,, reboot of the primary controller can fix it.

I have the same thing on MCD 6.0 and 7.1 and a reboot did not fix it.

I think it is the screen saver.

No screen saver as far as I know.

I think it loads the default screensaver and a help file. Those are the 2 files I see in MBG tftp cache

I can't think of any way to disable the loading of these.
It takes a long time for them to load when the phones go resilient.

Is there a firewall between the phones and the resilient controller?

No.
And it does the same thing when failing back to the primary controller.

I've seen it take up to 5 minutes or so when a large number of sets are involved in the handoff (over 300), but the only time I've had problems with the display showing longer than that was when there were firewall ports that needed to be opened between the sets. Can you grab a Wireshark trace from one of the sets? That might help you figure out if something is getting dropped or is configured incorrectly.

Interested if you come across anything.  We had huge problems with this after go live last year.  One was legit (vpn mtu), but then all phones were frozen on it for a long time.  (they can't blame the network when it's working great on metro-e)

"Changes" made were vague at best and I think rebooting is basically what he did.

I'd rather get rid of that message completely.

VPN MTU? Do you have any more information on this? I have been struggling with setting up a test environment in my test bench for a large deployment we are doing, but this one is a little different some of the other we have done and how the VPN is implemented, but the phones come mostly online and just stick on Applications Loading, local phones come up fine, everything else seems fine and I have been working with our IT Help Desk to get it working but nothing seems to help, but I don't think anyone has mentioned MTU size.

@acejavelin:  I will look back to last year's email and see if I can find details.  Here's what I remember:

- We went live and naturally problems started soon after.
- Was most notable with IPSEC sites since they would go offline frequently due to ISP.
- At the time our enterprise Wifi controller could not connect to the AP's over VPN.  MTU in the controller was 1500 or 1450 and we had to bump it down between 1375-1400.

- This lead us to look at the MTU on the 3300, though Mitel techs refused to change it.
- They insisted it was a network problem until phones at fiber and within LAN's of the 3300's did the same.
-- Pretty sure he even plugged a phone directly into the pbx and it did the same. (full disclosure: I did enjoy that part...)

- Tech reviewed and I think changed a few things, but ultimately said he didn't do much.
- Scheduled a reboot of one or both 3300's at night and that fixed the issue.

Question: If  you unplug/reboot a phone at non-VPN does it come up ok?  Part of our confusion is that all the phones on T1/Fiber sites were up for weeks prior to go-live and did not reboot.  Phones worked fine until you had to reboot or logout/hotdesk back in.

VPN:
From a quick review of the tunnel status, MTU is ranging from 1412 to 1436.  Specfiically 1436 on tunnels using 3des/sha1, DH:5.  Sites with 1412 use aes128 or 256/sha1 with a second proposal of 3des/sha1 and DH: 14.

I don't see that we are forcing MTU on either end.

I have a 5320e remotely that I use to test both teleworker/nat and over IPSEC.  Will see if I can break it when I get some time.  So far it's working fine in both scenarios.

A few searches didn't lead to much; kind of all over the place.  Try restarting the webserver?

Not to hijack Ralph's thread which did not seem to be related to VPN.  We have 370+ handsets and I haven't done a failover in quite awhile, maybe a good time to test again.
