Equallogic Email notification spamming!

Hi All,

Email notification keeps spamming whenever there is a issue from the same host. Every email had only 4 events in it.

Documentation says "The group attempts to combine multiple events into a single e-mail message to reduce the number of sent messages. A message will be delayed three minutes at most.". But I got 280 emails in just 2 minutes. 

Here is a screenshot of the errors in the logs. As you can see, the issue was with just one host, but every attempt was  a unique session (based on the port number??) so it kept triggering email alerts. Is there anyway reduce the time period of the email alerts and merge more events instead of just 4?
