Hi all
Our Xymon server has recently stopped sending alert emails. This server is
also running Postfix and is our mail relay.
From alert.log all I see is:
2024-01-31 02:17:39.813610 Whoops ! Failed to send message (Select(2)
failed)
2024-01-31 02:17:39.829027 -> Select failure while sending to Xymon

And notifications.log is zero bytes in size.
I added "--debug" to the "[alert]" section of /etc/xymon/tasks.cfg and
while the verbosity was increased, there was no indication of why alerts
are not being sent.
Any clues how I can debug this?
Thanks
