When using COBOL, specify environment variables as follows:

With COBOL/2:

Specify 0x00000efc for the environment variable

COBSIGMASK.

With COBOL85:

Specify 1 for the environment variable CBLCORE.

(This value is set by OpenTP1 as default.)

If the environment variables are not specified as shown in the above, troubleshooting is impossible because a core file is not created when the UAP process terminates abnormally.
