Hi everybody,
I've got a problem with tomcat since a week. It seems to be related
to the traffic, which is more important than usual these days. Tomcat
stops responding, wile the tomcat process is still running. Restaring
tomcat+apache makes everything working fine.
version information :
jakarta-tomcat-5.0.28
apache 2.0.54
Linux Mandriva 2006
JDK 1.5.0_05-b05
mod_jk 1.2
mod_jk.log :
[Thu Mar 02 11:13:58 2006] [error]
ajp_connection_tcp_get_message::jk_ajp_common.c (961): Can't receive
the response message from tomcat, network problems or tomcat is down
(127.0.0.1:8009), err=-104
[Thu Mar 02 11:13:58 2006] [error] ajp_get_reply::jk_ajp_common.c
(1503): Tomcat is down or refused connection. No response has been
sent to the client (yet)
[Thu Mar 02 11:13:58 2006] [info] ajp_service::jk_ajp_common.c
(1721): Receiving from tomcat failed, recoverable operation attempt=0
[Thu Mar 02 11:13:58 2006] [info] ajp_service::jk_ajp_common.c
(1749): Sending request to tomcat failed, recoverable operation
attempt=1
... and so on, until restart
mod_jk.conf is quite simple :
JkWorkersFile /usr/tomcat/current/conf/worker.properties
JkLogFile /etc/httpd/logs/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
... + 2 JkMount
Nothing in apache error_log, nor in catalina.out.
Tomcat and Apache are running with the same user (apache).
I was thinking about a problem of too many file descriptors opened ;
do you think it could be possible ? Is there a misconfiguration
somewhere ?
Have somebody encountered a similar problem ?
