I got postgres segfaults several times a day. Postgres log: Dec 9 21:15:07 goldbolt postgres[4515]: [292-1] user=,db= LOG: 00000: server process (PID 8354) was terminated by signal 11: Segmentation fault Dec 9 21:15:07 goldbolt postgres[4515]: [292-2] user=,db= LOCATION: LogChildExit, postmaster.c:2725 Dec 9 21:15:07 goldbolt postgres[4515]: [293-1] user=,db= LOG: 00000: terminating any other active server processes Dec 9 21:15:07 goldbolt postgres[4515]: [293-2] user=,db= LOCATION: HandleChildCrash, postmaster.c:2552 dmesg output: postmaster[8354]: segfault at 7fbfbde42ee2 ip 00000000004534d0 sp 00007fff4b220f90 error 4 in postgres[400000+446000] grsec: Segmentation fault occurred at 00007fbfbde42ee2 in /usr/local/postgres-8.4.1/bin/postgres[postmaster:8354] uid/euid:111/111 gid/egid:114/114, parent /usr/local/postgres-8.4.1/bin/postgres[postmaster:4515] uid/euid:111/111 gid/egid:114/114 Notes: - Postgres was built from source with --enable-thread-safety - Tried several kernels, no luck - I have psql on a different hardware, same problem happens there too - There are no sign of HW (memory, disk) errors - No other daemons (apache, nginx) segfault, only postgres The binaries are not stripped, how can I help finding the cause?
