Hello friends of libCurl,
for the first time, I observed the following trace with an select() error:
15045:259 About to connect() to proxy XXX.XXX.XXX.XXX port YYYY (#0)
15045:260 Trying XXX.XXX.XXX.XXX...
15045:277 curlSelect(): errno = 9, msg = Bad file descriptor

15046:125 curlSelect(): errno = 9, msg = Bad file descriptor

OS was QNX 6.3.2. libCurl version=7.19.3.
The select error occured during an endurance test.
The timestamps left are of format seconds:milliseconds.
select() returned -1 and the errno was 9 / EBADF / "Bad file descriptor"
15045:277 curlSelect(): errno = 9, msg = Bad file descriptor
curlSelect(): errno = 9, msg = Bad file descriptor [repeated
300 times]
15046:125 curlSelect(): errno = 9, msg = Bad file descriptor
For ~0,85 seconds the select() call returned that error. select() was
called ~300 times during that time.
After that, the HTTP 206 response has been received. So, at first sight,
the transfer has not been disturbed
by the select() error. I have not checked whether the data has not been
corrupted in some way.
What might be the reason for that error ?
Maybe it is a problem of the OS and has nothing to do with libCurl ?
Does anybody has also observed that kind of problem ?
How severe is that problem in general? Can it destabilize the whole
system (->crash) ?
Kind regards,
Stefan
