This is just a quick heads up. In our runup to the Sloan upgrade we encountered server wedges with AOLserver4 + nsopenssl 3.0 beta21.
The exact cause isn't yet known. Yesterday the server wedged again and happily Dossy and Don were on IRC and able to help me poke around the wedged process a bit with gdb.
The upshot is that while AOLserver4 is considered quite stable by itself, AOLserver4 + SSL isn't yet production ready.
Copious details here:
In the short term we've reverted back to AOLserver3. Once we've got the upgrade behind us, I'll set up a debug-compiled test version of the wedging environment, and maybe if we get lucky we'll be able to contribute some helpful QA back to the AOLserver and nsopenssl teams.
Many, many thanks to Dossy and Don for their help. Onward!
