Can anyone else confirm that or understand why the problem occurs?
Looking at the error messages described by Hector_UA it appears that the program (LFSStats) is causing LFS to send too much information to it.
Of course, LFS doesn't do that normally, so it must be that the program is asking for too much information from LFS all at once or it is failing to read the information that LFS is sending to it.
The result is that LFS is filling up the send buffer with information. It reaches 32K and then closes with the error "BUFFER SIZE".
