Steps to Reproduce

1. Install HFix-3577 and HFix-4345.
2. Call the Rule-Connect-SOAP and check the temporary files created.

Root Cause

A defect in Pegasystems’ code or rules. 

Due to a Bug in axis2 code PRPC creates high number of temporary files in the server temp directory which increases the file descriptor count.


Apply HFix-8815.
