Still on 4.3.7, on RHEL5.
Had a custom test fail and hang last night, a perl script called from tasks.cfg . Not sure if this is related. But six hours later xymon started failing wtih
2012-10-17 06:51:00 Whoops ! Failed to send message (Connection failed) 2012-10-17 06:51:00 -> Could not connect to Xymon daemon at 10.100.5.42:1984 (Connection refused) 2012-10-17 06:51:00 -> Recipient '10.100.5.42', timeout 15
drilling into detail pages was also failing.
Resetting fixed it and nobody thought to run the self test.
Betsy PS the self test I created was a file monitor that looks for /home/xymon/TESTOK . If that file exists it sends email to whatever addresses are in /home/xymon/testalert.txt . All of our support team has privilege to touch those two files, and the rule is the last one in alerts.cfg . Created this after munging up alerts.cfg so some pages were not going out.
