BCM 450 KEEPS LOCKING UP & NEEDING A REBOOT? 4

[uniquename4me]

I've been fighting with a BCM450 that has issue with IP sets all off-prem at one location, that one set gets kicked out and then they can't get it re-registered and eventually just register a different extension number? They tell me that other times when they try to register one number it kicks out another and again have to pick a different extension number? Now they're informing me that the main location locks up at times and will not process calls and they have to reboot to resolve the problem??

I've attached a copy of the alarms when this has occured and I'm wondering if anyone has some idea or solution on this?

Here it is:
54005 Mrs:: Shutting down due to MPS communication failure
50064 The Media Path Management sub-system unexpectedly became offiline-terminating
54005 Mrs:: Shutting down due to MPS communication failure
10014 Service Manager- Media Path Server (mps) has stopped unexpectedly. This will affect all IP Telephony. Service Manager is attempting to restart the service.
10229 Service Manager- Doorphone service has been stopped
10212 Servce Manger- Line Monitor Service has been stopped
10211 Service Manager- Computer Telephony Service (Cte) has been stopped
10206 Service Manager- Quality of service Monitor has been stopped
10314 Media Path Server (mps) has been succesfully restarted
10003 Service Manager- IP Terminal Service (UTPS) has stopped unexpectedly. This will affect all IP terminals on the system. Service Manager is attempting to restart the service.
10011 Service Manager- Computer Telephony (Cte) has stopped unexpectedly.
47009 FindMe/FollowMe. Registered Handoff Feature code F960
10212 Service Manager- Line Monitor Service has been stopped either
10211 Service Mangaer-
10303 Service Manager IP Terminal Service (UTPS) has been successfully restarted
10311

Thanks in advance! Let me know if someone has some ideas or direction.

I did find with an IT guy that he ran a program that identifies Packet Loss. Interestingly, it shows like a tracert and shows each step in the process with a graph and identifies which section of the route is losing packets with a percentage loss. I found that after it got handed off to a particular company stateside on route to overseas, there were packet loss both on the acceptance, internal switch handoffs and again on the final pass off to the next carrier that amounted to 20% packet loss. The one thing that I'd like to know is I've been fighting not only this problem of packet loss which has tended to vary on the BCM monitor showing 1 or 2 % packet lose up to 15%, but I'm more interested in knowing if anyone has had a major packet loss problem as it seems to be causing the BCM to lock up with a series of alarms starting with "Media Path Server has stopped unexpectedly". This causes a whole series of alarms that shut down services requiring either a manual reboot of the system or it does come back up on its own after a varied time interval from 5 minutes to more. Sometimes I'm told it even locks up the digital sets in the office preventing them from taking calls? It's almost like the BCM says "OK, I've had enough of these errors, I'm shutting down and rebooting to see if I can clear these problems". This has been ongoing with first a BCM50, then 2 different BCM450s. Anyone gone down the same road as unusual as it seems?

This has been an ongoing problem since you others have given replies to in the past. I have noticed that the remote sets that are off-prem in a few locations do remain connected in spite of issues with the other off-prem sites that share one location over in another country overseas. When complaints come in from them saying that they cannot register for example extension number 271, I can pick up a set here and register the extension with no problem whatsoever. Then I've told them the problem must be at there location so reboot their switch and equipment. This resolves the issue and their sets re-register with no problem. I've told them that for the sake of the cost of a switch to replace their POE switch and see if that resolves the problem. This has not been done?

I'm interested in knowing whether traffic problems at the remote site with the IP phones could bog up processing on the BCM450. I did do a cold reset on another BCM, and loading up the program manually with the intention of switching it out to see if that resolves the problem.
The IP sets overseas are on partial DHCP meaning they receive their local address from their router and then have the public IP loaded as there S1 and S2 addresses, so I don't know if there's anything that needs to be tried in changing settings remotely after reading an earlier post about setting the IP ranges.

Just to clarify, this problem occurs not only on the BCM450's that we've tried but also on a BCM50 which is also in place previously and seems to have the same problems. That's why I think it's the remote locations router/switch causing this issue.

Any further comments before I go back to trying to resolve this issue again?
