![]() ![]() ![]() 11:25:18.891 CEST WARNING: terminating connection because of crash of another server process 11:25:18.891 CEST LOG: terminating any other active server processes 11:25:18.891 CEST DETAIL: Failed process was running: SELECT * FROM transactionoutputs WHERE fileheader '' I got this message a lot during the night where I was not doing anything with it either.įor the actual error regarding the query from pgAdmin, this is what I get: 11:25:18.891 CEST LOG: server process (PID 20569) was terminated by signal 11: Segmentation fault It is showing this message for the default postgres database and not my own, but it still confuses me why this happens as I'm using the default postgres user for both databases. I am certain that I am using the correct password, as it does work 50% of the time of the queries. 19:43:26.959 CEST DETAIL: Password does not match for user "postgres".Ĭonnection matched pg_hba.conf line 102: "host all all all md5" The last few days, it constantly gave me the following message: 19:43:26.959 CEST FATAL: password authentication failed for user "postgres" The logs are not making much sense to me, but there are several things wrong. I did try to restart the service to no avail. What is weird is that the database has been running for over a month without any issues, and this only started today. I couldn't find any other examples where this happens in pgAdmin, but there is surely something wrong. This query specifically worked fine a few days ago. However, when I try to run the following query in pgAdmin, I get the message Connection to the server has been lost. Interestingly, the same queries (which are simple "SELECT * FROM table" statements) run perfectly fine in pgAdmin. This probably means the server terminated abnormally Server closed the connection unexpectedly I am using SQLAlchemy and it is giving me the following error: : terminating connection due to administrator command In about 50% of the cases, my Python script will fail to return any data because the DB server closed the connection. Since today, I am suddenly getting errors when querying data from a Python script running on the same machine, and in some edge cases also in pgAdmin 4. I am using PostgreSQL 12 on Ubuntu 18.04.I have a PostgreSQL 10.12 server running on an Ubuntu 18.04 Server. 04:40:51.239 CST LOG: server process (PID 18121) was terminated by signal 6: Aborted The rest of the logs from this time are about terminating connections because of a server process crash just like the WARNING from the original error. This is from what I can tell the relevant part of the log file from the last time it crashed when I tried this. Pg_basebackup: removing data directory "/var/lib/postgresql/12/main" Pg_basebackup: error: could not read COPY data: server closed the connection unexpectedly Pg_basebackup: error: could not receive data from WAL stream: SSL SYSCALL error: EOF detected HINT: In a moment you should be able to reconnect to the database and repeat your command. WARNING: terminating connection because of crash of another server processĭETAIL: The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory. ![]() The title is the part of the error that appears most relevant. This error usually happens at the very end of the backup but sometimes it also happens in the middle. I have tried increasing max_wal_senders to 20 and wal_sender_timeout to 600s but it is giving the same error. But as of this week, I had to use it again, and is failing with error below. I am running a WAL log shipping standby/backup server configuration, and I have been using pg_basebackup and to create a full backup of a PostgreSQL database without issues for awhile. ![]()
