Summary: httplib sporadically throws a TypeError

Initial Comment:
This is the output that occurs about 1 in 500 hits to any 
particular URL. I've only seen it so far hitting servers 
running Apache 1.3.20, but I don't have enough data to 
limit it to that.

Python 2.1.2 (#1, Mar 16 2002, 18:24:08)
[GCC 2.95.3 [FreeBSD] 20010315 (release)] on freebsd4

h = httplib.HTTPConnection(host)
response = h.getresponse()
data = response.read()
File "/usr/local/lib/python2.1/httplib.py", line 246, in read
value = value + self._safe_read(chunk_left)
File "/usr/local/lib/python2.1/httplib.py", line 314, in 
_safe_read
chunk = self.fp.read(amt)
TypeError: an integer is required

I'd give you the URLs but I don't think it matters that much, 
I've seen this problem now hitting 4 different machines, all 
running linux/apache. It's not something very easy for me to 
reproduce because I only see the exception thrown once or 
maybe twice during the day where there are 20,000 hits from 
my daemon that day. I suppose that the way to reproduce it 
would be to have a list of urls, and to just have an app sit 
there and cycle through them doing a GET every 5 seconds 
or so, and eventually it should show up. I suppose to be more 
accurate the app would have to be threaded as well, maybe 
having a thread for each url that just opens an 
HTTPConnection every 5 seconds.

Can you provide any more information about what URLs cause
problems?  You could call set_debuglevel(1) to enable output
of all  HTTP trafffic.  Or just a list of some of the URLs
that failed.
