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, -- Wei Yang | [log in to unmask] | 650-926-3338(O) ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XCACHE-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XCACHE-L&A=1
