Dirk, Thanks for looking at this :-)
The check that follows the last one in the log is another URL check for a different web site on the same web server. Both of these check for basic web site content and fail with an SMTP message and an SAMessenger message if the content does not exist. I've looked at the logs on the web server in question and there were indeed errors reported at this time the would have caused it to stop responding. (Time to patch it up to date) The SMTP server(s) used for alert messages are on different servers. All I did to make SA continue was reboot the Webserver in question.

So the blocking is caused by something that is done after that test. (could be the alerts or the next test for example). Also did you do something on the SA machine to make SA continue to work? The web server that was rebooted, was that also the SMTP server that should have been used for the alerts? What alerts do you use on the URL check entrY? dirk. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Steve Davis Sent: Fri Nov 29 10:31 AM To: '[EMAIL PROTECTED]' Subject: [SA-list] A failed check locks up Servers Alive Importance: High Hi, For some reason a website check that timed out last night completely locked up servers alive. Basically the web server failed, fine. Servers alive detected this in the log file but then stopped functioning. It didn't send any alerts either. It should have at least sent an SMTP message. We rebooted the web server this morning and as soon as it came up, servers alive sprung back to life.?! we're running servers alive v3.3.1132 on Windows NT 4, sp6a Why did this happen and how can I stop it? cheers Steve This is a clip from the log file (these are all private servers): 29 November 2002 03:14:00 Free space on \\lisa\d$ is : 11,754.23 MBytes 29 November 2002 03:14:06 Free space on \\marge\c$ is : 1,742.48 MBytes 29 November 2002 03:14:07 Free space on \\marge\d$ is : 9,501.67 MBytes 29 November 2002 03:14:20 Free space on \\homer\c$ is : 948.16 MBytes 29 November 2002 03:14:21 Free space on \\homer\d$ is : 12,902.37 MBytes 29 November 2002 03:14:28 Free space on \\poseidon\c$ is : 4,084.38 MBytes 29 November 2002 03:14:29 Free space on \\poseidon\d$ is : 17,120.24 MBytes 29 November 2002 03:14:29 Not checking host poseidon because of checking schedule 29 November 2002 03:14:31 Free space on \\hephaestus\c$ is : 18,066.18 MBytes 29 November 2002 03:14:32 Free space on \\hephaestus\d$ is : 19,004.25 MBytes 29 November 2002 03:14:32 Free space on \\hephaestus\e$ is : 38,255.43 MBytes 29 November 2002 03:24:35 Check cycle starts ( 1571- 1572) 29 November 2002 03:24:42 Free space on \\zeus\c$ is : 2,121.94 MBytes 29 November 2002 03:24:48 Free space on \\lisa\c$ is : 1,311.96 MBytes 29 November 2002 03:24:49 Free space on \\lisa\d$ is : 11,754.23 MBytes 29 November 2002 03:24:55 Free space on \\marge\c$ is : 1,742.48 MBytes 29 November 2002 03:24:56 Free space on \\marge\d$ is : 9,501.42 MBytes 29 November 2002 03:25:16 URL check (http://my.ebulletins.co.uk/) failed due to Timeout. 29 November 2002 08:46:55 Perfmon (\\homer\Processor(0)\% Processor Time) down 29 November 2002 08:46:56 ERR: connect to host failed: 53 29 November 2002 08:46:56 Can't do perfmon check, due to authentication problem 29 November 2002 08:46:56 Perfmon (\\homer\Processor(1)\% Processor Time) down 29 November 2002 08:46:56 ERR: connect to host failed: 53 It's usual for servers alive to fail the first round of checks after a server has been rebooted. The second check went through fine with everything working. ---------------------------------------------------------------------------- ----------------------------- This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
