br_util.log same error every 5 seconds on multiple NAS

Hi All,

Hoping for some help.

I have multiple qnap’s with container station installed and they all report :

[2026-11-10 22:22:06] Error: get bridge id from mapping table failed
[2026-11-10 22:22:11] Error: get bridge id from mapping table failed
[2026-11-10 22:22:16] Error: get bridge id from mapping table failed
[2026-11-10 22:22:21] Error: get bridge id from mapping table failed

every 5 seconds in file : /var/log/network/br_util.log

Running latest firmware and not doing anything especially funky with containers/virtual switches.

Could someone with container station installed quickly check and verify that they’re not getting these errors reported please.
If anyone has any ideas on a fix, appreciate the pointers/suggestions.

Thx!

Hi and welcome to the forum. :slight_smile:

What’s “latest” today, won’t necessarily be the “latest” a year from-now, which is going to be really frustrating for someone in the future reading this and not knowing if their issue is related, because they won’t know which version you’re talking-about.

Please: always use the full firmware version and build number when reporting an issue.

For the particular issue in your post, I also suggest including your installed Container Station version.

Yep - makes sense. Sorry about that.
Here’s the details.

Model : TS-464
FW : QTS 5.2.11.3661
Container Station ver : Version 3.1.2.1742 (2025/11/26)
