ISAPI-Problem
Hi,
I have the following problem on a Windows Server 2003 64Bit (AMD).
Configuration:
IIS 6, isapi_redirect.dll AMD64 Version 1.2.30, Tomcat 5.5.27, JDk 1.6.0_12 64Bit.
I am using the following small worker.properties:
ps=\
worker.list=ajp13
worker.ajp13.port=8010
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.ajp13.connection_pool_size=500
My isapi_redirect.properties contains only (no other parameters set)
extension_uri
log_file
log_level (error)
worker_file
worker_mount_file
My Tomcat site works fine in general, there are up to 1.400 users active and the site
answers requests very fast. However I have the following log entries every few minutes
(sometimes every few seconds) in jk.log. Every time that pair of entries:
[Wed Oct 27 12:15:37.764 2010] [3156:3284] [error] ajp_service::jk_ajp_common.c (2559): (ajp13) connecting to tomcat failed.
[Wed Oct 27 12:15:37.811 2010] [3156:3284] [error] HttpExtensionProc::jk_isapi_plugin.c (2195): service() failed with http error 500
And I do not have any other log entries in Tomcat- or Application Log. The client receives
an incomplete HTTP-Response, the response has no "Content-Length" header and no content,
for example.
Any hints or ideas?
Regards,
Jost

And here is whole response I receive, if I run into that error:

The html-body contains the response I would expect. Because there is no "Content-Length"-Header or
"chunked encoding" or "Connection: close" or what ever, a browser is not able to determine when
the response has to be closed. I looks like the browser hangs - until a timeout is triggered.
Like I said before: the request before was a request with a "Content-Length: 0"-Header (and no content)
and I suppose it has to do with the error afterwards.

Rainer,
I checked the complete log file. There are no other messages for hours, except these group of entries.
IIS was restarted at 01:30. However it sometimes says "closing socket -1". Looks strange, because I
think "-1" is not a valid socket number:
jk_ajp_common.c (1490): (ajp13_internet) did not receive END_RESPONSE, closing socket -1
Could the problem be related to http://issues.apache.org/bugzilla/show_bug.cgi?id=49413 that
was fixed in version 1.2.31? Or other AJP fixes in Tomcat since version 5.5.27?
I see some responses to earlier requests just before the error occurs with "content-length=0",
what is correct in that situation, but could that cause the error afterwards?

No, I copied it directly from the log file. I have always these 5 lines of output grouped together.
However I have the same lines in that case at 09:04:05.

Rainer,
that is the log output with log level "info":
[Fri Oct 29 09:04:15.312 2010] [3076:4308] [info] ajp_service::jk_ajp_common.c (2540): (ajp13_internet) sending request to tomcat failed
(recoverable), because of server error (attempt=1)
[Fri Oct 29 09:04:15.483 2010] [3076:4308] [info] ajp_send_request::jk_ajp_common.c (1490): (ajp13_internet) did not receive END_RESPONSE,
closing socket 1628
[Fri Oct 29 09:04:15.546 2010] [3076:4308] [info] ajp_service::jk_ajp_common.c (2540): (ajp13_internet) sending request to tomcat failed
(recoverable), because of server error (attempt=2)
[Fri Oct 29 09:04:15.593 2010] [3076:4308] [error] ajp_service::jk_ajp_common.c (2559): (ajp13_internet) connecting to tomcat failed.
[Fri Oct 29 09:04:15.655 2010] [3076:4308] [error] HttpExtensionProc::jk_isapi_plugin.c (2195): service() failed with http error 500
I still have no other info, in particular no log entry in Tomcat or my applications indicating an error in Tomcat or my apps.
The problem came in after we switched from Version 1.2.14 to 1.2.30 of the redirector dll.

Increase your log_level to "info". This will provide additional log
lines directly before the ones you cited which contain more detailed
information about the root cause.

I did not say "concurrent users". Just active sessions. There are,
under normal circumstances, not more than 50 conccurent requests.
