No, on that server I used 'xrootd-20050728-0310.i386_linux24.tgz' the provided binary tarball for RH7.2 so if debugging was there I should have it. > Per chance, did the executable change while xrootd was running?

While it is possible that a > massive core curruption occured, that seems highly unlikely. I can see from the logfile I was running 20050328-0656_dbg until the crash but the day before had changed a symbolic link to the 20050728-0310 xrootd package to be used in prevision for upgrade (but did not yet restart xrd/olbd then). So it looks like I am the one responsible for this crash... By the way... from the name it looks like I have the debugger (or does the _dbg suffix mean something else)? > On a second note.

This is something I asked the admins a week ago so it should be increased a day or another...
