I am experiencing a problem where the amount of update jobs in BITS Win service stuck in 'TRANSFERRED' state is constantly growing. When reaching the max limit (I think the default is 60), it causes OS crash. I need to manually clear the queue every day using bitsadmin:

bitsadmin /reset /allusers

I am running two Firefox installs

• Firefox Release (currently 127)
• Firefox Nightly (currently 129)

I have one profile for each and app.update.BITS.enabled set to false in both.

Here are two examples of jobs I had in the BITS queue this morning. Note that one is for Firefox Release and one for DevEdition. I have not ran DevEdition for a long time (but I have it installed on my machine). I haven't change the app.update.BITS.enabled in the profile for DevEdition.

What should I do to stop the BITS queue to grow?

Honza

I'm a bit confused what is going on in this bug. This appears to have been filed in response to the comment:

If you have further problems disabling the Background Update Agent that you would like to investigate, please file a different bug since this bug is for BITS specifically, not the Background Update Agent.

Yet this bug seems to be exclusively about the BITS problem, which Bug 1856462 already covers. The title mentions the Background Update Agent, but none of the bug description does.

Did you file this bug because you want to talk about the Background Update Agent? If so, could you update the bug to, like, describe the problem you are having with the Background Update Agent?

Please, feel free to update the title.

I don't know what the root cause of the problem is. I am seeking for a solution that would stop the BITS queue to grow and crash my system.
Happy to use any bug you recommend.
