system administration question, request for advice
netdata on the cybrespace matrix server has been reporting the following alarm at a steadily increasing rate over the last couple months: ip.tcp_accept_queue, "the average number of times the TCP accept queue of the kernel overflown, during the last minute"
this seems like the symptom of another problem, but i can't find much information about what it might be a symptom *of* (other than, possibly, a slow application not accepting connections fast enough).
can anyone advise? what should i be looking for to further diagnose the cause? what, if anything, could i do to mitigate this at the system level?
cybre.space users: apologies for recent federation delays, it seems during times of peak activity we've outgrown the number of sidekiq workers we've been using. i've scaled them up and hopefully the instance will perform better under load, but i'll be keeping an eye on things over the next few days to be sure.
#Introductions / Side C
There are few things which make me feel more tired, deep in my soul, than seeing a white woman espouse self-congratulatory rhetoric about how much she prioritizes “listening” and “personal growth”. My hope is that I will instead be able to demonstrate those things through my actions.
Still, I want to emphasize that my mentions/DMs are always open & available. I may not respond immediately, and I cannot provide therapy or crisis counselling. But if you donʼt know where else to turn, give me a go.
#Introductions / Side B
More about me: I have a website at https://go.KIBI.family, a journal at https://www.u2764.com, and a long history of publishing my thoughts online. I was the “backup admin” of glitch.social years ago, which meant that when the server exploded, I could confirm to everyone that yes, the server exploded. Then we all waited for the actual admin to wake up :P .
Since then I have been mostly just laying low, something which is extremely easy to do on Mastodon (PROTIP: if you donʼt follow anyone, nobody follows you).

periodic reminder that we run a matrix instance at https://matrix.cybre.space/
matrix is a modern (federated!) chat protocol with all the bells and whistles -- look for Riot in your favorite app repository / marketplace for a slick client that can connect to any matrix server
or you can use it on the web directly at https://matrix.cybre.space/
(join #meta:cybre.space if you're interested in discussion and updates about this instance and our matrix server)
okay, local folks: images should be back if you refresh the page
something's going wrong with the custom domain feature of digital ocean's CDN. it will serve images successfully if you query it directly, but not if queried via a CNAME (domain alias), which we use to point https://dostatic.cybre.space to digital ocean's endpoint
i'm going to file a ticket with digital ocean and change cybre.space's server configuration to use the CDN endpoint directly instead of via cname for the time being.

cybre.space is now on mastodon version 3.1.1!
release notes for 3.1 are available here: https://github.com/tootsuite/mastodon/releases/tag/v3.1.0
notable new features include:
- local-only admin announcements
- (cybre only) raised the character limit to 1024
if you spot any bugs, please let us know or file an issue at https://cybre.tech/cybrespace/mastodon
if your avatar or header image is broken due to the recent CDN change, it will probably be faster for you to just reupload it, since the CDN caches everything (even errors) with a turnover rate of ~1 hour
it looks as if some of the older media has lingering permissions issues (not a problem before because everything was being downloaded from DO by a privileged client), if you see a broken image let me know and i'll see if i can fix it
