When trying to send out a batch email to registrants of a particular event. I get the following error message (this is from the log, but it repeats itself down the page on the admin). It seems to eventually send the email to the users, but not until much later in the day. Not sure if the issue is because there are about 240 registrants. I notice it doesn’t throw the error when i just send it to one registrant.

Not sure if the issue is because there are about 240 registrants.
Possibly yes.
The server may be timing out during the request to generate all of the messages for the batch email.
If you try splitting the batch up into small sections, for example selecting 50 registrations in a groups and retrying does the batch email work then? You can also try higher values but it depends on your server.
