Hello,
I am into a frustrating situation about a router Cisco 2901 (Firewall + IPS installed) and at every few days (3 -4 days) I get no internet connection . After I restart the router , the internet connection works.
I have a small datacenter : 2 web servers Dell that host : DNS, Web, Email.
I have submited a case and the enginner told me that : "These errors are popped out when the controller is bad and according to some previous Service Request as raised with Cisco, an RMA has normally resolved the issue".
.......................................................
MSI 192, name: wic_mbrd_hdlc_error, hdlr 0x3069BCA0, cnt 1, ctx 0x0, slot 0, IO_Controller, ERR, number 0
MSI 193, name: wic_mbrd_hdlc_error, hdlr 0x3069BCA0, cnt 0, ctx 0x1, slot 0, IO_Controller, ERR, number 1
.......................................................
So they replaced the router with a new one . I have installed and configured the new router . I''m not a cisco specialist, I used Cisco configuration professional.
After 3 days after the new router installation I get again : "No internet connection" for ~30 minutes . After that I reset the router and then the internet connection works. The network was working.
This time I can access it I I get the logs :

I contact again suport case but I received an general answer that tells me that "this might happen due to a normal or abnormal event............".
Can somebody help me ?
If the memory was full , why the router don't try a release / renew command ? Is the a command that can tell the router : whenever the memory is full to release / renew it ?
I hae attached the router configuration .
