Thank you for the suggestion. I opened a ticket with Red Hat regarding this issue and so far we've found there is no limitation that would cause this. Also, we turned on auditd and found that although the program generating the mailx commands shows its sending them they are not being executed (at least not when it gets down to the last 90 or so, but it varies based on the number we are sending).
I've been monitoring at what point the emails stop and at first it was the 294th email, but since then it seems to vary. Any suggestions for an alternate service to send emails with?
