Yesterday migrated from OS 4.0.2 to 4.5.1
First of all i upgraded my Suse10.0 (kernel time zone patch)
With Suse 10.0 upgraded i passed to Zimbra OS 4.5.1
Yesterday all was good
but this morning ZCS didn't reply
i scan for 443 port but there was no response
instead port 7071 was good
so i use tomcat status but i had not reply
tomcat stop i had no reply
tomcat start i had no reply
I had a lot of messages deferred
so zmcontrol stop
wait a moment and verify with ps -U zimbra than zmcontrol start
All was ok!!
So i remembered that i increased the tmpfs partition from 150 to 300 Mb in my /etc/fstab and i had not any other deferred messages
So i went in /etc/fstab but my tmpfs row has been commented
#/dev/shm /opt/zimbra/amavisd-new-2.4.1/tmp tmpfs defaults,users,size=300m,mode=777 0 0

Now i find in zimbra forum Bug 13607 and Bug 12916 but i don't understand what exactly i have to do?
In my /opt/zimbra i find amavisd-new-2.4.3 too

Can i put?
/dev/shm /opt/zimbra/amavisd-new-2.4.3/tmp tmpfs defaults,users,size=300m,mode=777 0 0

I have to work with cron to clean amavis ... ?

I am afraid for other deferred message maybe when i am out of office
