Hi,
We have a mixture of CF10 and CF11 servers running on Windows 2012, IIS 8/8.5. On one CF10 server we have these errors consistently throughout the day in the isapi_redirect.log file:
[Tue Nov 18 08:58:50.130 2014] [10776:11284] [error] isapi_write_client::jk_isapi_plugin.c (1400): WriteClient failed with 1229 (0x000004cd)
[Tue Nov 18 08:58:50.281 2014] [10776:11284] [info] ajp_process_callback::jk_ajp_common.c (2089): Writing to client aborted or client network problems
[Tue Nov 18 08:58:50.356 2014] [10776:11284] [info] ajp_service::jk_ajp_common.c (2795): (cfusion) sending request to tomcat failed (unrecoverable), because of client write error (attempt=1)
[Tue Nov 18 08:58:50.416 2014] [10776:11284] [info] HttpExtensionProc::jk_isapi_plugin.c (2603): service() failed because client aborted connection
The connector is set to debug level INFO, yet we see INFO, WARN and ERROR status messages. We had this issue on CF10 update 12 and update 14.
Appreciate it someone could check their isapi_redirect.log log to see if they get these errors too. Are the errors normal (people closing connections with ESC key etc) or is there tuning to do, or is there a problem? Curiously, some of our servers have no such errors at all, except for the ISAPI connector starting up and shutting down and showing the number of connections etc. The only significant difference between the website with the errors and the ones without is that it uses more AJAX requests. Be grateful for any pointers.
