Hi,

I see errors when filling a tree in a file that is openend via xrootd. The 
problem gets worse, the more entries I try to fill.

(N.B. It's not that I consider it an efficient way to work, filling a remote
tree, but I was toying around with a few tests for our xrootd installation)

I attached a sample file with which I can reproduce the error.

.L xrootdFillTree.C+
xrootdFillTree(5000)
  [No error]
xrootdFillTree(10000)
Error in <TTree::Fill>: Failed filling branch:t1.px, nbytes=-1
Error in <TTree::Fill>: Failed filling branch:t1.py, nbytes=-1
Error in <TTree::Fill>: Failed filling branch:t1.pz, nbytes=-1

xrootdFillTree(20000)
  [2*above errors]

xrootdFillTree(30000)
  [3*above errors]

ROOT version: 5.11.02  (using xrootd-20060414-1334_dbg of the distribution)
arch: 
    Intel(R) XEON(TM) CPU 2.20GHz  
    and also Dual Core AMD Opteron(tm) Processor 280

Thanks,
Derek
