FTP client dies with error message "ftp: error in loading shared libraries: ftp: undefined symbol: fstat" when giving an interactive command to the 
client (dir, get etc.). Odd thing here is that it doesn't die if the client is invoked by pftp command. Setting the client to passive mode when 
invoked by ftp doesn't help. I have all applicable updated packages installed including the 2.2.16 kernel. If I remember correctly the problem first 
appeared after I switched to 2.2.16 kernel. I have an another machine with similar configuration which doesn't have this problem. Both machines 
were updated to 6.2 from 6.0.

Here's a log of what happens:
