Earlier today I received some automated email messages that one of my
customers web systems was acting up. They have some monitoring software
in place that said the systems were if down. Normally these types of
alerts would fire if there was a network problem or if 4D Client had
crashed. When I logged into their server to check things out I found the
web server and 4D Client running and no evidence that 4D Client had
crashed. I did note that the server seemed extremely unresponsive when
administering it remotely and when interacting with both their static
WebSTAR served pages and their dynamic Active4D pages.
I rebooted the system and things speeded up. I noticed a problem with
all of their Active4D pages, they are now blank. More specifically on
most browsers tested the page source revealed:
<html><body></body></html>
When trying those pages with MSIE on Windows I noted MSIE's "Page Not
Found" page with a 403 Not Allowed error.
Active4D 3.0
4D Client 6.8.4 on Mac OS 10.2.8
4D Server 6.8.4 on Win 2k Server
ITK Web Server
Modified ITK Shell that serves both A4D and "Netlink" style pages.*
WebSTAR 5.3.3, w/ Active4D proxied through WebSTAR **
* Note the netlink style pages serve OK. The majority of their web apps
have been converted to Active4D though.
** Thinking WebSTAR Rewrite might be getting in the way I turned off
WebSTAR and tried accessing the Active4D pages directly on port 8080.
Same blank pages.
I have some logging code in place that verifies that Active4D (the ITK
shell) is seeing the proper requests.
I've tried multiple reboots of both the web and db server machines. I've
repeatedly trashed the 4D Client res/rex, tcp.opt and 4DV6PRF files.
I've fixed file permissions on the OS X machine twice. Because I'm
working remotely I couldn't check the disk, but that is my first course
of action when I get on site tomorrow.
Does anyone here have any other ideas? This one has really got me stumped!
tia,
Brad Perkins
