## Symptoms

- On Security Gateways, the `cp_file_convert` process may unexpectedly stop responding producing a core dump and restart during Content Awareness inspection of malformed or complex PDF files.

## Cause

An issue in the crash-handling logic causes the system to restore the signal handler incorrectly during repeated PDF file processing. When the PDF conversion library encounters malformed input, the resulting exception is not consistently captured. This behavior causes unexpected termination and restart of `cp_file_convert`.

## Solution

This problem was fixed. The fix is included starting from:
