'initial sync of N groups' - for over an hour !

[Jason Vas Dias <jason.vas.dias@gmail.com>]

Please, is there any way to disable the 'initial sync' of groups with MA GNUS ?

I just built a fresh copy of Emacs 24.5 and tried out GNUS on my main GMAIL
account for the first time, having previously used it for my corporate account
and liked it .

BTW, I didn't like having to enable access by 'Less Secure Apps' in
GMail Settings ! :
https://support.google.com/accounts/answer/6010255
What can I do to get google to think MA GNUS is secure ? Is SSL / TLS
/ STARTTLS not enough ? I have tried them all, and both the 'login'
and
'cram-md5' authentication methods.

I am running under Oracle Linux 7 (OEL7), on an x86_64 box.

But having set up my connection in ~/.gnus :
<quote><pre>
(setq gnus-select-method
      '(nnimap "Gmail"
        (nnimap-address "imap.gmail.com")
        (nnimap-server-port "993")
        (nnimap-inbox "INBOX")
        (nnimap-stream ssl)
        (nnimap-record-commands)
       ))
(setq smtpmail-smtp-service 587)
</pre></quote>

,  and doing 'M-x gnus' for the first time in Emacs 24.5 ,
GNUS has now spent over an hour in the 'initial sync of 32 groups' state ,
and has not displayed anything or updated its counter after reaching 162996k  .

Here is a gdb stack trace of the (now stuck) Emacs process:
