I use WordPress 2.0.2 which contains a copy of Snoopy
I recently ran into a problem where the PHP script
would simply terminate with no feedback whatsoever
during a call to fread() in the _httprequest() function
while my wp-slimstat plugin was activated.
After many hours of debugging, I found that changing
the default value of $maxlength from 500000 to 8192
fixed the problem.
I think that the default value should be permanently
changed to 8192, because according to the PHP
documentation on fread()
reading of file will stop at 8192 bytes anyway, so
having the value of $maxlength any higher would be
pointless, and in my case, cause problems.
