For the record:
We have an instance of Xcache to serve CVMFS for SLAC batch nodes. It crashed this morning after receiving ~9.5K non-handshake connections from sn160.s02.sjc01.qualys.com in 5 seconds (did our friend Artem Harutyunyan used to work at Qualys? I know he left a long time ago).
I donšt know if there is a remedy to this. I will setup a firewall rule before I restarting the Xcache.
regards,
