Subject OutOfMemoryError on email notifications
Date Sun, 13 Dec 2015 22:55:43 GMT
Hi,

i just tried the relatively new email notification feature with version 2.2 and keep running
into an OOME when notifications are about to be sent:

agents process ran out of memory - shutting down
java.lang.OutOfMemoryError: Java heap space

Looked into the code
There is a never incrementing for loop (copy&paste bug, loop runs over j and increments
i) at EmailConnector.java in line 298:

    for (int j = 0; j < childNode.getChildCount(); i++) {

Regards,
Markus
