can root files be too long?

Dear Rene and Fons,

I have written a conversion program for our FPACK/BOS
DST into a root tree file. Root saves 25% of disk space :-)

Everything works, except that if I test with 10 times
the events I cannnot open the file. I get the following error
message:
-rw-r--r-- 1 kohne h1 524250001 Dec 3 12:48 CDST2.C9620001.root

root [2] TFile("/h1wgs/h1mpim1/x01/usr/kohne/CDST2.C9620001.root");
Error in <TFile::Read>: error reading all requested bytes from file
/h1wgs/h1mpim1/x01/usr/kohne/CDST2.C9620001.root, got 0 of 231

leaving root then causes a *** Break *** segmentation violation.

cheers
Jobst
