Issue with mail notifications.

What steps will reproduce the problem?

Email motifications works correctly during one or two days but it stop sending 
emails. 
After restart tomcat all the mails in the queue are sent. (If we restart tomcat 
before the mails are deleted from the queue) and continuous working for one or 
two days.

We set TRACE to log level, but we couln't find any information on the log that 
could help us to identify the issue. We only found one diference in logs entries

When the email works this the log entries are:

2014-11-05 10:09:30, DEBUG, util.Helper, token email added to send queue for 
XXXXXXXX@XXXXX.XXX
2014-11-05 10:09:31, TRACE, servlet.ResourceFileServlet, GET request for: 
/GestionCuenta/public/resources/nonce-i23bu8a5/flags/png/es.png (no params) 
2014-11-05 10:09:31, DEBUG, server.RestServerHelper, {2wo} REST WebService 
Request: GET request for: /GestionCuenta/public/rest/app-data/client (no 
params)  [X.X.X.X]
2014-11-05 10:09:35, DEBUG, queue.EmailQueueManager, successfully sent 
authenticated email: from: XXXXX@XXXXX.XXX, to: XXXXX@XXXXX.com, subject: 
XXXXXXXXXXX

As you can see in this log, the mail is stored in the queue and after that the 
email is sent.

When the email is not send the log entries are:

2014-11-05 11:29:13, DEBUG, util.Helper, token email added to send queue for 
XXXXXXXX@XXXX.XXX
2014-11-05 11:29:13, TRACE, servlet.ResourceFileServlet, GET request for: 
/GestionCuenta/public/resources/nonce-i23bu8a5/flags/png/es.png (no params) 
2014-11-05 11:29:14, DEBUG, server.RestServerHelper, {2vu} REST WebService 
Request: GET request for: /GestionCuenta/public/rest/app-data/client (no 
params)  [X.X.X.X]

As you can see the mail is added in the queue but never sent until we restart 
tomcat.

There are no error in the log or any relevant information between the last time 
a mail was sent and the first that fails.
