Hello guys
We have a problem with one of our web servers. The main Westminster web site
is stopping of its own accord on a semi-regular basis. When this happens,
the web server is alive and kicking, IIS is running, the CF Services are
running but the actual website defined in IIS is in stopped status. We have
two servers in a cluster, WESWEB01 being the master and WESWEB02 being the
slave. Load balancing is managed by ClusterCATS of which I have next to no
experience in.
Overview of problem:
- Seems to have started since implementing a scheduled CF Restart several
weeks ago.
- Seems to occur at a very similar time to the CF Restart
- Does not happen everyday - but every few days or so.
- WESWEB02 CF restart occurs 1/2 hour before (7am) WESWEB01 CF restart.
Whenever there is some significant problem on server - the message referring
to 'failure connecting to getmetricdataXML.cfm' seems to be present. There
is a call to this file in the IIS log every minute. What is is for?
I have been through the NT Event Viewer Application log on the web server
for the time period from when the CF Restart happens/website stops working
until the time that the service is manually restarted via PCAnywhere. I have
put all of the messages in an XL sheet which can be viewed at
<http://fclounge.cfdeveloper.co.uk/wesweb01log.xls>
http://fclounge.cfdeveloper.co.uk/wesweb01log.xls (the first worksheet on
the left "Application Log on Event Viewer" shows the main info). There is a
column of comments of things which I am not sure about.
I would very very much appreciate if any body with any knowledge in this
area could spare a few minutes of their time to have a look at the XL file
above and provide some feedback/direction for me. Westminster are very keen
to get this resolved quickly as this is giving downtime for the site at a
time that they are being externally monitored and I am at a bit of a loss
about the exact cause/resolution of the problem.
I also have records of the IIS logs, CF Application log messages and CF
server log messages if these would provide any more help.
Thanks
