Hi Arya,

This exception occurs whenever the system is under heavy load. Try tuning up the memory settings on the VM, to help overcome this problem.

Even chk with this

1. go to TCODE: SWEL and check if you have any errors over there

2. go to TCODE: SWF_XI_CUSTOMIZING

maintaint runtime environment

configure RFC destination

and check if the password for user WF-BATCH is correct

pls chk out

Hey,

Jco call is executed when Abap stack calls java stack.

In your scenario when the Interface determination(abap stack) refers to the interface mapping(java stack) Jco call will be executed.

hence you can do the following things.

refresh your abap stack. go yo transcation SXI_CACHE and do complete cache refresh.

refresk your java stack:

use this url: http://<hostname>:<port>/CPACache/refresh/mode=full?

you can also reassign the interface mapping in the interface determination.

reward points if useful.

Hi Deb

Did u do a "test connection" for all the JCO connections?

The solution is to fix the hostname on Gateway Options at Transaction SM59 to the AI_DIRECTORY_JCOSERVER and AI_RUNTIME_JCOSERVER destinations.
