Hello, we do observe that when copying a file the client is stalled for some time. 180417 19:17:28 17252 schroete.97360:7@qc08 XrootdProtocol: 0100 stalling client for 5 sec Sometimes it is for 10sec and this gets repeated without a recognizable pattern. The client is not stalled when the copied file is removed at once and recopied. It looks like a similar issue as this one: https://listserv.slac.stanford.edu/cgi-bin/wa?A2=ind1203&L=XROOTD-L&P=R598&1=XROOTD-L&9=A&I=-3&J=on&d=No+Match%3BMatch%3BMatches&z=4 Is this a settable parameter or something we did wron in our setup ? We have one redirector and 12 data server on a 10GBit network. Client access is very limited because this is a test setup.
