When you powering off or unplug WXC from network it cannot trigger/initiate any signal to external device to reload.
When you remove WXC from network, the WCCP neighboring with WXC will be broken on core switch, So I suspect WCCP protocol might trigger anonymous reboot of core switch.
If core switch reboots due to an know/unknown IOS caveat/bug or software failure, then it does create crachinfo before it reloads.
Check logging errors; if core switch reloads then it would be erased from switch, so if customer has syslog server configured, then check whether any abnormal logs appearing before core switch reload.
It will help you to narrow down the issue.
If crashinfo was created on core switch, then I suggest you to analysis the issue switch TAC team.
