We had a minor site hiccup today. All seems to be working, now.
We have always been open and upfront about the site, so in the interests of full disclosure here is a summary of the problem and steps taken to fix it.
tl;dr Comment counts shown for each story on the main page seem to have stopped getting updated since about midnight this morning; appears to be working now. Please accept our apologies for any who were inconvenienced.
Read on past the fold for details.
Problem: Comment counts on the main page showed "0" comments on recent stories, but opening a story showed the correct number of comments for it.
Actions Taken:
1.) Try bouncing the front-end servers to restart apache (This is a low-risk step that seems to fix a surprising number of issues).
No joy.
2.) Ask for help on the #dev channel on IRC.
Ncommander replied asking if slashd (an over-seeing daemon for the site) was running.
Looked through my log files and on the site wiki; determined that slashd should be running on server: fluorine
ps -AF | grep slashd | wc showed 32 processes
Ncommander suggested: killall -9 slashd
Try: killall -9 slashd
"No process found."
Inspection of output of PS -AF suggested this one-liner should do it:
$(ps -AF | grep slashd | awk '{print "kill -9 " $2}' )
Got most of the processes, but there still seemed to be some stragglers.
/etc/init.d/./slash stop
/etc/init.d/./slash restart
Conclusion:
Looked like it might have worked... reloaded main page... see updated comment counts!
Looks like all is working again.
It's a credit to the staff here that the site has been running so smoothly and without crashing or hiccups for... I can't remember when we last had an outage. Given that in the early days of the site we had maybe a few hours of uptime between crashes, we have come a long ways!
I'm going to assume this is one of those "have you tried turning it off and back on again" kind of problems, and unless the problem re-occurs, assume it is solved.
Need to hurry to get to work, so I apologize for the brevity of this posting.

Accounting application, not that cool, but it pays the bills. As I have described on SN previously, customers given a choice, prefer to subscribe to it in the cloud even when offered an option to install it on their own equipment.
It's not like the math is complicated. Although the application is complex in its sheer size, database design complexity, etc.
That is one feature on Wikipedia Tables, and also other web sites that I despise.
My employer does not do any monkey business. It's not our business model. That includes not trying to collect and sell information.
The server backend is Java on a beefy server. Front end browser is JS code. There are 3rd party libs (example jquery) but served from our servers. Nothing is pulled from a 3rd party site. No frames. Strictly SSL/TLS.
The lower I set my standards the more accomplishments I have.
