Hi John,

I followed your suggestions.

(1) With -bfs - -redir -single , I got a deadlock problem: webbot hangs
up on a _read operation (It ran 3 times and got the same problem):

HTTP........ Generating HTTP/1.x Request Headers
HTTP........ Generating General Headers
Buffer...... Flushing 1253a8
Write Socket 251 bytes written to 15

#0  0xff1955fc in _read () from /usr/lib/libc.so.1

(2) With -bfs only, it works much better. It runs for about 10 minutes
but it ends with the following problem.

HTTimer.c:201 Timer ffbef240 not found

The last traces have been:
