I am getting this dump occasionally from OpenERP, but it seems harmless. The code serves HTTP; is this dump what happens when a connection is dropped?
Exception happened during processing of request from ('10.100.2.71', 42799)
Traceback (most recent call last):

This just means that the underlying TCP connection was abruptly dropped. In this case it means that you are trying to write data to a socket that has already been closed on the other side (by the client). It is harmless, it means that while your server was sending an HTTP response to the client (browser) she stopped the request (closed the browser for example).

issue solved and its cause one static file with .mp4 type is causing the browsers to block connection I remove it and everything works fine.
I have a simple server application, communicating with a mongodb server, running on the port 1234. Sometimes i find the application hanging (not down, it would be better...) and this error on the log

**error: [Errno 32] Broken pipe**
I read about 'broken pipe' error and how to avoid it, but i don't really know when does it occur... So, there's a way to reproduce the problem or to debug it?
I don't know if the question makes sense without fully explaining what the server does, actually, but if i don't get some clue of the situation, I can't explain better than this...

The video file of all formats is working perfectly in all browsers and Android devices. When I try to access it from an iOS device. It gives me the above error. As you can see in error, first it is giving me response as 200 and then there is broken pipe. What does this broken pipe even mean? Just FYI, I have already posted a question stating that I can't play video on iOS devices, I am now posting a new question because I found this error in my terminal.
How do i fix this issue? Any help is appreciated.
This is beacause django is handling your media files not apache.Try by changing you configuration in server.
For example inside your apache2 edit example.com.conf file add following lines so that apache will serve media files.
**Alias /media /your project path/media**
Sometimes this may fix this issue.
I have a very simple API server built on top of bottle. What is does is to just return a JSON upon being called, the content of the JSON being a random string. It works great.
This server was scanned yesterday by a vulnerability scanner (nessus) and crashed because of a misbehavior of the scanner. I include the Traceback information below which shows a error: [Errno 10054] An existing connection was forcibly closed by the remote host exception.
My question is the following: who is the one who should handle this problem?
Is this nessus, which does unholy things? On the one hand yes, it should behave in a standard way (this is a scanner which, among others, is used for industrial scans where it meets all sorts of devices and should attempt to mitigate the risk of crashes). On the other hand life is brutal and the receiving end (what is scanned) should be able to cope.
Is this bottle ? It is a framework which should handle typical and not so typical web traffic and leave to the programmer the task of handling the business logic and not the internals
Is this me? handling all the possible exceptions
I am asking as I would like to help improve either nessus or bottle (or myself) - this is not strictly a programming problem ("how to catch the exception") so if you really feel so, vote to close as opinion-based, though I ask anyway as I see it as a "programmers methodology" question.
