Hi
I am having problems with the mod_jk module 1.2.26 and Tomcat Native
connectors running in Solaris 10.
The problem occurs in both processors x86 (64-bit) and sparc (64-bit).
(The problem does not occur on RedHat EL5 64-bit).
On the mod_jk workers.properties file I am specifying a value for
reply_timeout:
worker.localworker.reply_timeout=10000 (10 seconds)
I am anticipating that some requests would need more time, so I
decided to run my test suite just increasing the value to 30000.
Oddly, with this value and running the same set of tests I get
sporadic errors. The mod_jk log shows the following message when this
occurs:
[error] ajp_get_reply::jk_ajp_common.c (1730) : (localworker) Timeout
with waiting reply from tomcat. Tomcat is down, stopped or nertwork
problems (errno=145)
I am using the following components:
Apache Web Server 2.2.11
APR 1.3.3
APR-util 1.3.4
openssl-0.9.8
mod_jk 1.2.26
Tomcat 6.0.16
Tomcat Native Connectors 1.1.12 (using same APR version
as Apache)
jsvc
Sun Java JDK 1.6
I also found that the problem only occurs if the Tomcat Native
Connectors is enabled in Tomcat.
I can't figure why increasing the reply timeout would actually
produce the errors it is supposed to prevent!!
Any help is appreciated. I would like to benefit from the Tomcat
Native Connectors, but I can't figure what I am configuring wrong.
