[GENERAL] org.postgresql.util.PSQLException: FATAL: terminating connection dueto administrator command

Hello,

Running psql table updates() by using
org.springframework.scheduling.quartz.JobDetailFactoryBean cronjob from
web application. Got the following exception:

org.postgresql.util.PSQLException: FATAL: terminating connection due to
administrator command


Re-run the same cronjob several times, and cannot re-generate the error.

May I know what might cause the above error message please? And which
log file(online doc) could help provide more detail information about
this please?

Thanks a lot.
