Good Morning,
I'm repeatedly getting a session killed error while trying to run a series of queries:
/opt/postgres/9.1/bin/psql: line 30: 5560 Killed LD_PRELOAD=$PLL LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PG_BIN_PATH/../lib "$PG_BIN_PATH/psql.bin" "$@"
/opt/postgres/9.1/bin/psql: line 30: 5701 Killed LD_PRELOAD=$PLL LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PG_BIN_PATH/../lib "$PG_BIN_PATH/psql.bin" "$@"
/opt/postgres/9.1/bin/psql: line 30: 5781 Killed LD_PRELOAD=$PLL LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PG_BIN_PATH/../lib "$PG_BIN_PATH/psql.bin" "$@"
I'm not seeing a whole lot about this error online. Has anyone else run into this issue? I'm thinking it is a memory problem but am not sure. I'm not the system administrator, just the dba.
Here's a vmstat run:
