This is on win32/5.0.2
I receive an eof error when accessing a web page. Backtrace below.
This happens occasionally, every second or third call to HTTP-REQUEST, without regular pattern, when the call is made from a muproc thread. My code works fine when called from the ide.
I suspect that the proper initial bindings should be made when the thread is spawned, but I was not able to get this done.
Any help would be very welcome.

LispWorks, I assume.

Hmm, hard to say without a reproducible test case. Does it happen only with specific URLs or with arbitrary ones?

Which initial bindings are you thinking of?

What urls are you trying to fetch? If they are local ones that are known to be good that's one thing, but if your downloading from the general internet EOF and other errors are likely. To debug this we'll need more information.
FWIW, I have used drakma to download millions of pages of data and have not seen the problem you where every few fetches we get an EOF. We do often see errors but those are just errors in the environment (lost network connection, badly behaving server, etc).
