Hello,

we have the following configuration:

S.O. : Red Hat Enterprise Linux Server release 6.5

Apache : 2.2.15

Coldfusion 10 Standard update 12

SElinux disable

Iptables disable

Configuring / etc / httpd / conf / mod_jk.conf

# Load mod_jk module

Jk_module LoadModule " / opt/coldfusion10/config/wsconfig/1/mod_jk.so "

# Where to find workers.properties

JkWorkersFile " / opt/coldfusion10/config/wsconfig/1/workers.properties "

JkMountFile " / opt/coldfusion10/config/wsconfig/1/uriworkermap.properties "

# Where to put jk logs

JkLogFile " / opt/coldfusion10/config/wsconfig/1/mod_jk.log "

# Where to put jk shared memory

JkShmFile " / opt/coldfusion10/config/wsconfig/1/jk_shm "

# Set the jk log level [debug / error / info]

JkLogLevel info

# Select the timestamp log format

JkLogStampFormat " [ % a% b % d% H:% M: % S % Y ]"

AddHandler jakarta- servlet. Cfm . Cfml . Cfc . Cfr. Cfswf

In the log / opt/coldfusion10/config/wsconfig/1/mod_jk.log observe the following errors:

[ Tue Dec 03 10:29:53 2013] [ 3754:140076806252512 ] [info ] jk_ajp_common.c ajp_process_callback :: (1954 ) : Writing to client aborted or client network problems

[ Tue Dec 03 10:29:53 2013] [ 3754:140076806252512 ] [info ] jk_ajp_common.c ajp_service :: ( 2629 😞 ( cfusion ) sending request to tomcat failed ( unrecoverable ) , Because of client write error ( attempt = 1 )

[ Tue Dec 03 10:29:53 2013] [ 3754:140076806252512 ] [info ] jk_handler :: mod_jk.c ( 2718 ) : Aborting connection for worker = cfusion

Can anyone tell how to solve this problem because the connection between apache and coldfusion degrade coming to collapse the system.

    Not my particular environment Linux Apache however the way I read the mod_jk log content is very similar or same as this other thread and  detail in isapi_redirect log on Windows IIS environment.

    Thread:
    http://forums.adobe.com/message/5878493#5878493

    MOD_JK log sample:

    [info ] jk_ajp_common.c ajp_process_callback :: (1954 ) :
    Writing to client aborted or client network problems

    [info ] jk_ajp_common.c ajp_service :: ( 2629 ):
    ( cfusion ) sending request to tomcat failed ( unrecoverable ) ,
    Because of client write error ( attempt = 1 )

    [info ] jk_handler :: mod_jk.c ( 2718 ) :
    Aborting connection for worker = cfusion


    ISAPI_redirect log sample:

    [info] ajp_process_callback::jk_ajp_common.c (1984):
    Writing to client aborted or client network problems

    [info] ajp_service::jk_ajp_common.c (2684):
    (cfusion) sending request to tomcat failed (unrecoverable),
    because of client write error (attempt=1)

    [info] HttpExtensionProc::jk_isapi_plugin.c (2289):
    service() failed because client aborted connection


    Where I am seeing that sequence of log, CF10 IIS is not having any issue so it may not actually relate to the CF10 not responding. I would like to find a glossary of tomcat messages and the meaning however I have not got an
    interpretation to that log sequence. I will add the sites for me that have those logs have BYO wireless clients and it would be fair to say those users do not log off CF application however just close their browser or lid of laptop. Neither have I been able to reproduce the environment to cause that log detail so merely guess from me rather than statement of fact.

    HTH, Carl.
