Hi Andrew,

I just added a counter on the XrdPfc/XrdPfc.cc:

45 int ct = 0;
656 ct++;
658 cout << "GSTREAM" << ct << endl;

The error occurred on XrdPfc/XrdPfcInfo.cc:

543 TRACE(Warning, trace_pfx << "Corrupted access record,
skipping.");
618 TRACE(Warning, trace_pfx << "Corrupted access record,
skipping.");

and XrdPfc/XrdPfcFile.cc:

201 TRACEF(Error, "ioActive for io " << io <<" called on a closed
file. This should not happen.");

Thank you!
