how to find application that is opening proccesses When running ps as root within my device (HTC Desire HD)
I see the following line:

app_132   18584 13586 0      0     ffffffff 00000000 Z ratc


Repeating hundreds of times.

How can I tell which app is "app_132" ?

UPDATE:
O.k. I actually found out which app it was based on the class names listed at the end of first lines in the output of the ps command where app_132 is listed.

ps | grep app_132 | more


but even though this solves my immediate situation I still would like an answer to the original Q.
The numbers in "app_XYZ" name will be different on every device, since they depend on the order of installed apps.

In adb shell or terminal emulator perform the following command:

ls -l /data/data/


This should return a listing of installed apps' directories that contain their data and settings, like so:

drwxr-x--x app_1    app_1             2012-03-28 09:07 com.android.backupconfirm
drwxr-x--x app_2    app_2             2012-04-04 09:37 com.android.bluetooth
drwxr-x--x app_3    app_3             2012-03-28 09:07 com.android.browser

The 2nd and 3rd columns list the app's owner, while the 5th column contains the app's package name.  Find the line corresponding to the "app_132" from your logcat entry, and the package name will help you figure out the responsible app.

Once you have the package name, try searching for it in the Google Play Store.  Just use the link https://play.google.com/store/apps/details?id=xxxxxxx, where "xxxxxxx" is the package name you found.  For example, on my phone "app_70" corresponds to "com.android.chrome", which corresponds to Google Chrome browser in the Play Store: https://play.google.com/store/apps/details?id=com.android.chrome
