COM-Error unkown shown in the background SNP heuristic log

Dear Experts,

I ran an SNP Heristic in the background. After the job completed, I looked at the SNP log and saw the COM error unknown below:

COM - error unknown

Message no. /SAPAPO/OM001

A COM routine has encountered a program error.

The program will be terminated.

Can you please tell me what caused this error message? How to correct this problem?

Thank you,

Tom
