It is possible that this may be related to the problem you are seeing (I am not sure at this point).
I tried loading some packages from squeaksource a few minutes ago, and it was slow but functional. However, checking the image I see 15 active SSession handlers in a ProcessBrowser. This is not right, and it appears to be a recurrence of a problem that we have seen previously on an intermittent basis, both on squeaksource.com and (probably) on source.squeak.org.
I will terminate the runaway session handler processes, which I hope will clear up the immediate problem.
More to follow I'm sure ...

I think we should we should delete the "ATTENTION!" line but leave the note about creation of projects being disabled.
Yep.

Thanks David, it went back to normal speed for a moment, but is now rejecting my upload requests again (most will timeout, some do work intermittently)...

The image is now showing 10 session handler processes in the process browser. Presumably these are related to the failed upload requests.
I do not understand the cause of this problem, and it may be that I should revert the changes that I did earlier today (in which I put squeaksource under the control of the supervise(8) for starting the image).
But I suspect that the problem lies elsewhere, so for I will make a copy of the broken image for debugging, then terminate the excess processes. This should clear the problem temporarily. I will follow up with another email within about 30 minutes.

Attached is a screen shot of the process browser in the squeaksource.com image, showing the excess SSSession processes. They are deadlocked on accessing DateAndTime now, which contains a critical section using the LastTickSemaphore in class DateAndTime.
In the squeaksource.com image, LastTickSemaphore has 0 excess signals, whereas in other images I look at, it has 1 excess signal. This looks to me like a mutex that has gotten confused.
I sent a signal to LastTickSemaphore in class DateAndTime, and now it looks like a mutex again. Let's see if that clears the problem.
This certainly has a bad smell about it :-( But I note also that we are running our SqueakSource services on older images, and a number of changes have been made to DateAndTime since then.
Nicolas, I will send private email to give you the VNC password for access to the squeaksource.com image in case you need it (I am going to get some sleep soon).
