559790 - job queue fails to work silently

Status: RESOLVED DUPLICATE of bug 538705

(Bugzilla :: Email Notifications, defect)

Description

[WL]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.3a5pre) Gecko/20100414 Minefield/3.7a5pre
Build Identifier: 3.4.6 release

I'm using gmail as bugzilla admin and send all those mails from this email address via SMTP. As gmail have a daily send quota, I hacked bugzilla's mailer to try another email accout if this one refused to work. It works like a charm for many days. 
But recently, I found the job in queue kept increasing and never send one email out. I checked the daemon, it's running. I checked the /var/log/messages also, but get no clue.
Any one could help here?

Reproducible: Always

jobqueue restart can make it work again for several hours.
