Your latest code is giving me troubles. Integration test killed xrootd, the tail of the log is similar to what you observed intermittently:

I saved full log here:

/home/becla/qserv-run/2015_08/var/log/worker/xrootd.log

I hope we will be able to resolve it very soon, if we won’t, backup plan:

a) back off all changes

b) disable the code that is causing xrootd to die while you investigate

I’ll try to debug it tonight
