Hi,
Thank you for looking into my problem. The server is running an
antivirus and is in IPv4. I am not sure what you mean by user accounts
running IIS and Tomcat. They are started as a Windows Service. No
changes have been done on the system. Before the IIS Web Server crash
(Feb 26, 2010), everything was working fine. After the crash the
server was rebooted and this was when the issue started happening. We
were also getting a permission denied (warning messages Event Viewer)
when we tried to access the site. Event logs showed IIS still crashing
(Error) and ISAPI dll not loading but in IIS, ISAPI filter is green.
I have requested a system restore prior to the crash, looking back
maybe I should have re-installed the IIS first instead but time was
the essence and I really believed the system restore would work. The
restore did not work although I do not see the error messages on the
error log but I still see warning messages on Event logs for
permission denied when we setup the Web Site to run on port 80 and
443. We had to change the Http and Https ports to remove it from the
load balancing scheme in production.
I am not sure that I understand precisely everything you are mentioning
above, but the following (re-ordered to show each Tomcat with its ports
together), seems to indicate that everything is fine Tomcat-wise.
Tomcat #1 :
TCP 0.0.0.0:8088 0.0.0.0:0 LISTENING
6224 [tomcat5.exe]
TCP 0.0.0.0:8109 0.0.0.0:0 LISTENING
6224 [tomcat5.exe]
TCP 0.0.0.0:8188 0.0.0.0:0 LISTENING
TCP 127.0.0.1:8005 0.0.0.0:0 LISTENING
6224 [tomcat5.exe]
Tomcat #2 :
TCP 0.0.0.0:8188 0.0.0.0:0 LISTENING
7136 [tomcat5.exe]
TCP 0.0.0.0:8209 0.0.0.0:0 LISTENING
7136 [tomcat5.exe]
TCP 127.0.0.1:8105 0.0.0.0:0 LISTENING
7136 [tomcat5.exe]
Tomcat #3 :
TCP 0.0.0.0:8288 0.0.0.0:0 LISTENING
4280 [tomcat5.exe]
TCP 0.0.0.0:8309 0.0.0.0:0 LISTENING
4280 [tomcat5.exe]
TCP 127.0.0.1:8205 0.0.0.0:0 LISTENING
4280 [tomcat5.exe]
Tomcat #4 :
TCP 0.0.0.0:8388 0.0.0.0:0 LISTENING
4232 [tomcat5.exe]
TCP 0.0.0.0:8409 0.0.0.0:0 LISTENING
4232 [tomcat5.exe]
TCP 127.0.0.1:8305 0.0.0.0:0 LISTENING
4232 [tomcat5.exe]
So, each Tomcat listens on
- a shutdown connector (ports 8005,8105,8205,8305).
- a HTTP connector (ports 8088,8188,8288,8388)
- a AJP connector (ports 8109,8209,8309,8409)
You have checked that from a command window of the same host you can
access port 8309 (with a telnet client in this case).
From an earlier post, you also say that if you access (from a browser)
the HTTP port of Tomcat directly, it works fine.
So for all intents and purposes, it looks as if the Tomcats themselves
are fine.
This leaves the IIS side of things (including isapi_redirect, the IIS
side of the AJP conector).
I am not quite sure about the "permission denied" and "ISAPI dll not
loading", but basically after a system crash under Windows, I would
consider all this as suspect.
Maybe for a start, you could de-install the isapi connector, and
re-install it ? (save your config files, they look fine too).
Also, as Konstantin mentioned, replace "localhost" in your
workers.properties by "127.0.0.1", just to remove any ambiguity.
Also try to disable the virus guard and anything similar (Windows
firewall) that might interfere, just for a test.
