Summary0003060: sogod eats 100% CPU and all RAM and hang when via ActiveSync and Client try to connect Dovecot 1.2
Description

We use a Debian Squeeze (old stable) VM as Mailserver with Dovecot 1.2 and on a Debian Wheezy (stable) VM we run SOGo in actual Version 2.2.13.
When a ActiveSync Client connects to SOGo and SOGo open a connection to the remote Dovecot, the sogod hangs and eat 100% of CPU and do nothing.
strace of this process shows no output. After some minutes, wenn all sogod are hang, no more clients can connect the SOGo-Server. It reports
"sogod [17703]: [ERROR] <0x0x7f646a08be90[WOWatchDog]> No child available to handle incoming request!"

Settings:
"PREFORK=5" in /etc/default/sogo

Steps To Reproduce

run a Dovecot 1.2 IMAP-Server
run a SOGo 2.2.13 Server
enable ActiveSync
connect the an Android device to SOGo and try to sync mails.
