Follow-up Comment #1, bug #90686 (project xrootd): I found more of similiar cases when a server is running many open/write/close operations and get's restarted: The error comes from: XrdXrootdXeq.cc:2305 return Response.Send(kXR_FSError, myFile->XrdSfsp->error.getErrText()); Looking at the program flow, it is not guaranteed that myFile is a valid pointer. _______________________________________________________ Reply to this item at: <http://savannah.cern.ch/bugs/?90686> _______________________________________________ Message sent via/by LCG Savannah http://savannah.cern.ch/ ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-DEV list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-DEV&A=1
