To me it looks like the element Seller_SD (Custom Decision Element?) is causing memory leak and eating all your VXML servers native memory.

How many custom elements do you have running in your environment?

what is the value see you in below registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software 
Foundation\Procrun2.0\VXMLServer\Parameters\Java\Options

can you paste the key value for option here?

also, please attach recent tomcat logs covering the issue from C:\Cisco\CVP\VXMLServer\Tomcat

HI Chintan,

  We have several custom application deployed in our server (CVP 12.6.1), often getting memory leak and we need to restart the server to start processing.

Below are the values in the regedit

-XX:NewSize=1024m
-XX:MaxNewSize=1024m
-XX:Metaspacesize=512m
-XX:MaxMetaspacesize=512m

we dont have -XX:PermSize in the regedit, can we create this and also Could you please suggest, what is the maximum that we can set for below 6 values,

-XX:NewSize=?
-XX:MaxNewSize=?

-XX:Metaspacesize=?
-XX:MaxMetaspacesize=?

-XX:PermSize (not configured, can we configure )?

-XX:MaxPermSize (not configured, can we configure )?
