Issue/Introduction

Randomly, the following SEVERE_ERROR appears in the stdlog of the Application servers:

SEVERE_ERROR allocator.c 527 Allocator BPData free chain pointer 0000026F03FCEB90 references a corrupted allocator

NX_SPEL_DISABLE_ALLOC and NX_MAIL_DISABLE_ALLOC are installed in the APP Servers.

The error does not seem to cause any problem or impact in the SDM application.

Environment

SDM AA 17.x

Cause

Problem allocating memory to the SDM process, causing this issue to occur.

Resolution

Take a backup of the NX.env before implementing the following changes:

1. Disable Fast Memory by installing the following option in the NX.ev:

@NX_NOFASTMEM=1

2. Restart the service and monitor for the issue. 

Note: By default, SDM has a feature called FAST MEMORY. When FAST MEMORY is off (@NX_NOFASTMEM=1), we let the system handle the allocation and deallocation of new objects, thus, there might be a small tiny performance hit, probably not noticeable.

Implement the changes above in the DEV environment before implementing in a Production environment.
