Core Dump Occurs Due to Incorrect Settings of GUC Parameter log_directory

Symptom

After the database process is started, a core dump occurs and no log is recorded.

Cause Analysis

The directory specified by GUC parameter log_directory cannot be read or you do not have permissions to access this directory. As a result, the verification fails during the database startup, and the program exits through the panic log.

Procedure

Set log_directory to a valid directory. For details, see log_directory.
