What exactly happened here?
this was the setup, no routers at both end, isp was directly terminated on Wan0
PC---coreswitch---WanCore ( A )----100Mbps P2P link---WanCore ( B )---coreswitch---PC
Did icmp pings drop completely?
without data transfer yes network is up, when I started data transfer after some MB downloads, CPU utilzation went High on B End & network went down. in graph I see only 35% utilized, but when we saw physically on web interface during the issue it was to the peak.
Was the web interface up?
Machine was up, but not webinterface, nor no network. we had to hard reboot to make machine up.
What did the logs say?

How did you fix it?
We had to hard reboot B end machine.
Is this running as a VM/ which hypervisor? (since you mentioned in another thread that you can't get the HDD image to work)
Its Physical machine
What are the hardware specs?
A End:
Core i5
8GB RAM
500GB SATA HDD 7200RPM
B End:
Core i3
4GB RAM
320GB HDD 5400RPM
How much disk space is available?
100% free other than wanos folders, files & OS
Are any extra sites configured in MultiSite?
no
How are the tests done (tools/protocols/files)?
Started with FTP to test
Utilization during testing:
A End:
CPU:5%
Memory: 240MB
Disk I/O: 35%
Disk Usage: 35MB
B End:
CPU: 35%
Memory: 160MB
Disk I/O: 80%
Disk Usage:34MB
Later: at B End we configured similar conf machine which is of A end, but still it fails in Core--Core, Core--Edge, Edge--Edge.
