[cisco-voip] IPCC-Express version 4 FailSafe mode / error

[Afzal Bhutta]

Hello all,

I am facing failsafe error in IPCC express version 4 in our contact/sevice
center.IPCC integrated with CUCM version 4.1.3.We have 7835 servers (PUB
and IPCC) running 4.0 with 50 agents.Hard disk Total capacity is 36 GB only
1.7GB space left and Ram is 2GB this is in PUB server.Where as in IPCC
server RAM is 4GB and 36GB of Hard disk.

What I have notice to login into the Publisher server the CPU performance
is 100% every few second to few minutes.The CPU performance is fine at IPCC
server and at sub server.The jtapi provider is registered with pub 1st then
sub 2nd.

where as call processing is done by sub 1st then pub.Also in IPPC the jtapi
is registered with pub and sub host name not with IPs.We have DNS
environment.

What I have done so for when the cpu goes to 100% usage on that we did 2 to
3 test call from the PSTN to the call centre number and the call centre IP
phones goes into failsafe mode.(Meaning all phones ringing at the same
time).So we are able to create this kind of error by ouself.So atleast we
find that this is due to high use of cpu in pub.

I am not 100% sure exactly this is causing or something else or Is it
hardware or application issue?

I need expert views on this topic and please explore some of other issues
related to this error.

You help and expert views are really very much appreciated.

Thanks,
