I got some about 8-10 minutes ago. Borek said we should report it or make a post about it when it happens, so I'm doing that now. I was unable to submit my post for a while. I got the same error when I reloaded a couple of times. Then I left the computer for a couple of minutes, and reloaded again when I came back. This time it worked.

k, I'll check the logs
Or maybe it's was around 1pm. I can't aee my last login time anymore.
 
I got one at 10:58 (MST) while responding to a post in Systems & Design. One subsequently occurred when I tried to report it here. Now it seems to work, but the thread that I was responding to is gone. Are those related?

Hard to say not knowing what the thread was.

"Design for lorry under-ride guard"? Deleted, it was a crosspost.

Yeah, that's the one. Where's the live copy?

Thanks Borek. That's the same guy, and the same general topic, but absolutely not the one that I responded to. I have nothing to offer, so I won't bother pursuing the matter.
 
About 5 minutes ago several 500 errors from nginx when trying to send a PM.
 
I got a couple more during the night, but just went back to sleep without noting the time.
 
Got a 500 nginx error when replying to a thread about 1800 UK time.

Thanks for all the reports. Strangely I can't find anything in the error logs. It seems everyone is getting the error when sending information to the database?

The 502 and 504s were just trying to view threads, not posting anything.
 
In my case it definitely looked this way - I was able to browse, but not able to send PM.
 
I was also getting these last night, about 12 hours ago. I posted fine. I went to post again, and got the error. I logged out fine. Logging in, same error

Yes, I was getting them last night when I tried to delete a post, then again when I tried to report I was getting them.
 
I think these errors are sporadic, I just received a 'Database Error' when moving between the forums and then clicked back and everything was okay..
 
In my cases, it was always while attempting to post. Browsing presented no problems. Most were 500's, with a couple of 502's and possibly a 501 (I can't remember). I don't even know what the hell they mean, but they're annoying.

Likewise. I only got to 500 errors when trying to post. However, browsing was intact.

I managed to log out. But trying to log back in I got 500 server errors. I made a post at the same time on a status update on PF's Facebook page (roughly 11 hours ago).

I didn't dare attempt to answer the random question on the feedback form (the Contact Us form at the bottom of the webpage), because I didn't know what W stands for in an equation. Having those kind of questions, however, aren't helpful as a capcha, especially when one is trying to inform the admin of server errors. Especially when I cannot log in, nor if I was, couldn't post.

I made a tweak a few minutes ago.
I didn't smell anything, but I'll take your word for it...
