Hi,

I am trying to use libcurl in one of our projects. Many thanks to the curl community for such a great product!

Most of the transfers occur just fine however after some 20-50 downloads the library may get in this state where it hangs for (literally) 600sec. I set the timeout to 20sec reducing the hang period to that, however I get the following error: Operation timed out with 2508 out of -1 bytes received. The error was probably occuring without the shorter timeout I did not pay attention to that case. The number of bytes received matches the size of the document I am trying to download. The timeout occurs on various documents.

Of course when I turn on debugging this problem goes away. It looks like there is some problem decoding content-length or similar. Any pointers?

More details:
I am using curl-7.9.8 on win32. My application is multithreaded however a specific curl thread is accessed from just one thread. I implemented my own function to write the result to a file. I am using transfers from specified IP addresses or localhost, I do not need to do DNS lookups. I am downloading from a tomcat server and I requested HTTP/1.1, at least the transfers I debugged are re-using the existing socket. Although the application is multithreaded this problem occurs even with just one thread active - the other threads hold curl handles but do not perform any operation on them.

Thanks,

Marius
