[BUG]

[ahaghgoo]

Describe the bug:

• Postgres crashes when importing large OPML file. Now postgres keeps crashing on startup. Here is what I see on the backend logs:

Postgres:

2023-01-01 11:34:42.286 UTC [1] LOG:  starting PostgreSQL 13.9 on x86_64-pc-linux-musl, compiled by gcc (Alpine 12.2.1_git20220924-r4) 12.2.1 20220924, 64-bit

TTRSS:

Exception while creating PDO object:SQLSTATE[08006] [7] connection to server at "database.postgres" (172.29.8.2), port 5432 failed: Connection refused`
    Is the server running on that host and accepting TCP/IP connections?

Have you googled?

• Yes, but I couldn't find anything on what to do in order to clean up postgres database within docker and to prevent this from happening again.

Deployment method

• docker-compose
• ttrss image: wangqiru/ttrss:latest
• postgres image: postgres:13-alpine

Deployment environment

• OS: QNAP NAS QuTS hero FW h4.5.4.2217
• Browser: Safari 16.1 (18614.2.9.1.12)

To Reproduce
Steps to reproduce the behavior:

• I've linked to my OPML file here:
  https://drive.google.com/open?id=1kprkvWyC6EekArOPPhX-9RZxF6PcjTc-&authuser=ahaghgoo%40g.ucla.edu&usp=drive_fs

• All I did is import the file and TTRSS would populate articles but midway through fetching articles it would crash and it would no longer be accessible.

Expected behavior

• I would be able to import my OPML file with no issues.

Either your storage is full or you don't enough permission to write on the mounted directory
