<DIV><FONT color=#000080>On GFS client I echo "aaaaaaaaaaaaaaa"

the file was lost. So on client I couldn't read 11 correct, I " ll
-h ",the file is appear again in 92.249,but have not the right "<FONT
color=#000080>aaaaaaaaaaaaaaa",it was like "@@@@@@@@@@@" messy code ! If i copy
11 from 92.250 to 92.249, on GFS client I read the right file
"aaaaaaaaaaaaaaa" . Was that my configuring wrong ? why the file not renew
accurate?</FONT></DIV>
