Description:

Hi,

While a running a vacuum, the database crashed for 20 seconds and went into
recovery mode.

< 2016-12-12 08:52:25.163 UTC >LOG:  server process (PID 40436) was
terminated by signal 11: Segmentation fault
< 2016-12-12 08:52:25.163 UTC >DETAIL:  Failed process was running: VACUUM
(FREEZE, VERBOSE, ANALYZE);
< 2016-12-12 08:52:25.163 UTC >LOG:  terminating any other active server
processes

INFO:  analyzing "public.<<table>>"
INFO:  "<<table>>": scanned 150000 of 14701352 pages, containing 6786398
live rows and 1026 dead rows; 150000 rows in sample, 665186112 estimated
total rows
vacuumdb: vacuuming of database "" failed: server closed the connection
unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.

In /var/messages/log

000000000045da6c sp 00007ffe597fd7e0 error 4 in postgres[400000+519000]

Can you please help on what might be the issue?

Thanks and regards
Lara

You don't share much information here :(
Do you have at least a core file or a backtrace?
