Yes, My understanding is that the lock file is probably what fixed it. man is not very informative. We could look for answers in rsync source code but it's not worth the effort to me at the moment. Thank you all for your time.

Looking at the log, I can see you connect every four hours so I guess this is working fine now.

Around 5pm:

Unfortunately, rsync doesn't log connections that it forbids itself…

Here's the log:

@ArielGlenn, I've enabled logging on your module. I'll post the results tomorrow.

Ah! Kinda glad to read it because it confirms our hunch: your script misbehaves somehow and end up opening several connections: that limit of 2 only applies to you.

@Hokwelum @ArielGlenn, we've updated our config and you should update yours. The rsync module has now changed from download.kiwix.org to wmf.download.kiwix.org

@Hokwelum, we've decided to separate the official-mirrors and the public/anonymous services. This should prevent random slot grabbing by anonymous users. This would also be a safer base to investigate any additional issue in the future. @Kelson and I will be in touch with the contact person for this mirror to update the link (it's a different module).

No, this is not due to a mirror being full. As I mentioned before, we don't have much spare slots and this is an open server. At the moment for instance, 12.138.99.218 is using one slot. @Kelson should we increase our number of slots?

That disk-full issue on a (foreign) mirror was first resolved then happened again. It was eventually fixed on October 18th.

@Legoktm, thanks for the tip. It doesn't seem to work though. I'm always getting an error such as:
