Hello Andre Warnier,
Thanks for the response. My main problem is apache process is increasing ve=
ry fast and reaching to count 259 thereby bringing donw application.
For that i took thread dump also and tried to analyze but unable to find ou=
t what is causing the issue.
I have also posted some part of thread dump in another post.
I would liek to know why apache process is going so high in just 15 minuted=
and not coming down.
I would need all experts help to resolve this issue.

Hi.
After your other post, entitled "Need help in understanding tomcat thread d=
ump", it is a bit confusing now what your real problem is.
That other post shows that you are runnig some java modules on your tomcat =
server, which seem to have something to do with the same supplier (Ericsson=
?) than the one some Apache processes are connecting to using mod_jk.
We have no idea here of your applications, what they are doing, if it is no=
rmal or not that they connect to an Internet server of the Ericsson company=
, and so on.
Let's restart from the beginning, your original post :
>I am facing very weird problem of apache porcess going high upto 259 and i=
ncreasing again even after restart of backend server ie. tomcat.
So, is it the Apache httpd processes (children) that "go very high" (meanin=
g that there are many, too many ?), or the back-end Tomcat threads ?
What is the problem ? is it in Apache httpd, or in Tomcat ? does your serve=
r stop responding ? is it slow ? does it not do what it is supposed to do ?
>Apache version :- 2.0.59
Tomcat Version :- 5.5.9
Apache/Tomcat connectivity :- mod_jk
Both of the Apache httpd and Tomcat versions that you mention above are ver=
y old (many years).=A0 You should upgrade to more recent versions.
You do not indicate a version for mod_jk, but it is probably old also.
>when i have checked mod_jk.log file i am seeing this messages in the logs.

These messages look to me as if, in your Apache httpd server, there are pro=
cesses which communicate directly, through mod_jk, with a (real) external I=
nternet server "erib2bdev.ericsson.net" (probably a Tomcat server also).
That's all I can say.=A0 I do not know if that is your problem, or if these=
connections are a "normal" part of your application, or anything else.
Only you can know that.
Try to be a bit more specific about what the real problem is, and maybe we =
can start helping you.
Come on, give us a clue.
