    Description

      After a standard OS security update the housekeeper process suddenly get's SIGSEGVed, see zabbix-housekeeper-sigsegv.log

      Postgresql itself only sees a vanishing connection: zabbix-postgresql.log
      It seems to happen right after the select itemid,min(clock) from history_uint group by itemid query finishes.

      I attached via strace. But the log is not very helpfull: zabbix-housekeeper-strace.log

      So far, a package downgrade, OS restart etc. has not helped. Befor the OS level updates postgresql was presenting an error to the housekeeper that did not seem to create any SIGSEGV:

      2022-06-28 07:12:10 CEST STATEMENT:  delete from history_uint where itemid=74542 and clock<1655788142
      2022-06-28 07:12:10 CEST ERROR:  could not access status of transaction 138739714
      2022-06-28 07:12:10 CEST DETAIL:  Could not open file "pg_subtrans/0845": No such file or directory.
      

      This postgresql error is no longer present after OS level updates and a reboot. But now housekeeper no longer works.
