# [DFWD_TRASHED_RED_ZONE](https://apps.juniper.net/syslog-explorer/?msg=DFWD_TRASHED_RED_ZONE)

## SYSLOG Details
- **Message**: Trashed red zone pointer in block <variable>address</variable>
- **Help**: DFWD found a memory error while de-allocating heap memory
- **Description**: When DFWD is allocating heap memory, it uses a private memory allocator that writes a special pattern at the end of each allocated segment of heap memory. Later, when de-allocating this memory, DFWD checks for the pattern. If it does not find the previously written pattern, it means the memory was overwritten, which indicates a wild-write in DFWD.
- **Type**: Internal: Internal log message
- **Severity**: error
- **Cause**: DFWD bug. DFWD wrote more bytes than allocated by malloc for the region length.
- **Action**: Contact your technical support representative.
- **Attributes**: address
- **Facility**: LOG_DAEMON
