[Bug 55722] New: can't receive the response header message from
tomcat, network problems or tomcat (127.0.0.1:8009) is down (errno=11)
https://issues.apache.org/bugzilla/show_bug.cgi?id=55722
Bug ID: 55722
Summary: can't receive the response header message from tomcat,
network problems or tomcat (127.0.0.1:8009) is down
(errno=11)
Product: Tomcat Connectors
Version: 1.2.30
Hardware: PC
OS: Linux
Status: NEW
Severity: blocker
Priority: P2
Component: mod_jk
Assignee: dev@tomcat.apache.org
Reporter: sujeet_ssv@rediffmail.com
Hi
We are intermittently getting the HTTP 504 error with message "HTTP: 504 -
timed out waiting for gateway" while executing webservice call. The frequency
of this kind of errors is too less less than 0.02%. However this is very
critical from business perspective and even that % of error tolerance is also
not acceptable.
We tried to dig down through different logs but we were able to trace
correlated exceptions pertaining to these Http 504 errors in mod_jk logs only.
Below is the excerpt from mod_jk logs.

For reference-
Workers.properties ( on 04)
[root@some-server-in conf]$ cat workers.properties
worker.list=worker1
# Set properties for worker1 (ajp13)
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009

worker.worker1.cachesize=30
worker.worker1.cache_timeout=600
worker.worker1.socket_keepalive=1
worker.worker1.socket_timeout=300
We ran more than 10 endurance tests of 16 hrs duration however we are getting
these kind of exception consistently. Expert comments how to tackle this really
appreciated. Thanks
Sujeet
