Hi folks,

i am using libcurl in my c/c++ projects for a while and I like it a lot.

In my latest project I have at least 2 threads. 1 thread performs many
multi actions. the other thread sometimes makes some normal easy calls.
Each thread uses its own easy handles. Nothing is shared between the
threads. But all requests go to the same server (e.g. www.amazon.de)!

Sometimes the easy actions don't finish well. I get an error like that:
"* Operation timed out after 10570 milliseconds with 59283 out of -1
bytes received"

This does not happen always.

In the easy handle I specify my own CURLOPT_WRITEFUNCTION and set
CURLOPT_TIMEOUT. If i dont set CURLOPT_TIMEOUT the easy action hangs
"forever".

Can anyone help me with that bevaiour?

I am using:
* linux 3.8.2-1~experimental.1 (Debian)
* gcc (Debian 4.7.2-5) 4.7.2
* libcurl version 7.29.0

Here is the complete verbose output:
* About to connect() to www.amazon.de port 80 (#264)
* Trying 176.32.108.185...
* Connected to www.amazon.de (176.32.108.185) port 80 (#264)
