Hi,
I'm running into the following problem. In IMAP idle mode I'm waiting for
data using the select method. The connection is unencrypted / normal
socket connection. Everything seems to work fine but after some time
select returns immediately and returns 1 which means that one file
descriptor has data to read. When I read the socket I just get 0 byte
back. So there is actually nothing to read. Since I try to read a complete
line this results in a busy loop...
The IMAP connection is still working fine and I still can fetch mails or
getting IDLE notifications... Only select does not wait any more!
This weird behaviour always occurs after the server send a special
response (it says that there is a new message, which actually is not
there, and that this message has removed again). Since the IMAP connection
is still working afterwards I'm not sure why this trigger the failure of
select.
Could somebody take a look at *) line 203. Is there something wrong with
the usage of select?
Any idea why select stops working probably?
Regards,
Clemens
