Здравсвуйте.

Последнее время стало настораживать странное поведение postgres во время
бекапа (pg_dump, потаблично). Понятно, что лочатся таблицы, но настораживает
вот этот кусок лога:

Sep 7 01:01:55 db1 postgres[15320]: [6-1] user=,db= LOG: server process
(PID 7442) was terminated by signal 9: Killed

Настораживает что 'was terminated by signal 9: Killed'. Это нормальное
поведение?

При этом с db-машины нету коннектов, помимо коннекта от pg_dump, все
остальные коннекты - с других хостов от jboss и tomcat, используется
hibernate.
