roundcube and php 5.4.33: fgets(): SSL read operation timed out

[Michael Grimm]

Hi --

My setup: roundcube-1.0.2 + nginx-1.6.2 in a FreeBSD-10 jail. RC will connect to a recent dovecot server in another jail at the same host.

Recently, after upgrading php from 5.4.32 to 5.4.33 roundcube will refuse to connect to dovecot:

|	roundcube: PHP Warning:  fgets(): SSL read operation timed out in \
|	/...path2rc.../roundcube/program/lib/Roundcube/rcube_imap_generic.php on line 200

Recompiling every port involved and restarting both involved jails hasn't been successful. Only, reverting back to php 5.4.32 made RC work again.

Is anyone running into this as well?
Any idea how to debug this?

Thanks and regards,
Michael
