This is what I see in a stack trace Program received signal SIGSEGV, Segmentation fault. 0x000000000084dcf3 in pglz_decompress () -----Original Message----- From: Tom Lane [mailto:tgl@xxxxxxxxxxxxx] Sent: Tuesday, June 12, 2018 1:45 PM To: Heinemann, Manfred (IMS) <HeinemannM@xxxxxxxxxx> Cc: pgsql-admin@xxxxxxxxxxxxxxxxxxxx Subject: Re: Segmentation fault with parallelism PG 10.4 "Heinemann, Manfred (IMS)" <HeinemannM@xxxxxxxxxx> writes: > We allow some user querying against the database and a user wrote sql that would repeatedly cause a segmentation fault. We can't share the data but I will show what I can. The info you've provided is not of much help, but if you could show a stack trace from the point of the segfault, that might narrow things down. https://wiki.postgresql.org/wiki/Generating_a_stack_trace_of_a_PostgreSQL_backend regards, tom lane ________________________________ Information in this e-mail may be confidential.
