could not open file "base/XX/XX": Interrupted system call

Hi,

I am running the postgres docker image with that version:

2023-09-20 10:36:32.478 CEST [1] LOG:  starting PostgreSQL 13.12 (Debian 13.12-1.pgdg120+1) on x86_64-pc-linux-gnu,
compiledby gcc (Debian 12.2.0-14) 12.2.0, 64-bit 
2023-09-20 10:36:32.564 CEST [1] LOG:  listening on IPv4 address "0.0.0.0", port 5432
2023-09-20 10:36:32.564 CEST [1] LOG:  listening on IPv6 address "::", port 5432

And this is happening for some queries:

2023-09-20 10:38:25.076 CEST [47] ERROR:  could not open file "base/16386/17328": Interrupted system call
2023-09-20 10:38:41.897 CEST [49] ERROR:  could not open file "base/16386/68359": Interrupted system call

I can enter the container and view the files above with e.g. strings
$file | less and I can create a md5sum from that file without an error.

What can I do about that EINTR on open, how to fix it?

The host (6.1.53-060153-generic #202309130436 SMP PREEMPT_DYNAMIC) and
the docker daemon (Version: 24.0.6) do have nothing suspicious in there
dmesg / logs.

Anyone an idea how to debug / progress with that one?

Torsten
