A variation can give unexpected errors rather than unexpected data:

XrdCl::File *f = new XrdCl::File();
f->Open("root://me@pmpe01:1194//f1", XrdCl::OpenFlags::Read);
f->Read(0,5,buf,bytesRead,0); // gets 5 bytes from file 'f1' ok

sleep(20); // during this time the Xrootd server on port 1194 is restarted

XrdCl::File *f2 = new XrdCl::File();
f2->Open("root://me@pmpe01:1194//pww1", XrdCl::OpenFlags::Read);
f2->Read(0,5,buf,bytesRead,0); // gets bytes from file 'pww1' ok
f2->Close();
delete f2;

sleep(330);
// during this time the default TTL (300s for dataserver) expires and connection is closed

f2 = new XrdCl::File();
f2->Open("root://me@pmpe01:1194//pww1", XrdCl::OpenFlags::Read);
f2->Read(0,5,buf,bytesRead,0); // reads bytes from 'pww1' ok
f->Close();
delete f;

f2->Read(0,5,buf,bytesRead,0); // gives an error "read does not refer to an open file" or EBADF.
