XSP2 crashes serving static images

Question

Hi,

Requesting a simple HTML page with a jpg image makes XSP2 crash. If I remove the image from the HTML then the page is served OK all the time.

The version is XSP2 2.0 mono 2.6.1. the version 2.4.2.2 in the same machine works fine.

I have tested it in two different machines, both Windows Vista Business SP1.

Anyone has experienced the same? Any clue of what can be the problem?

Below is the stack trace displayed by the console: (The line in Spanish says "it has been forced the interruption of an existing connection by the remote host")

EDIT:

since another user is having the same problem I have submited a bug to Novell and created a litle zip to reproduce the problem: https://bugzilla.novell.com/show_bug.cgi?id=582162

Peer unexpectedly closed the connection on write. Closing our end.

Thank you.

Hi!

I have the same problem with Mono 2.6.1 running in Windows XP SP3. I use XSP 1.0, and I get exactly the same stack trace in the console. I don't have this problem using an older release of Mono.

I can't see my web page using Mozilla Firefox. I wait and wait, but the page keeps loading all the time without showing text or images. If I select the option that displays the source code, I can see it's ok and complete, but nothing appears in the browser. I can only see the title and the icon of the page.

Using Internet Explorer it's different. I have to restart the server sometimes and reload the page, but I finally see it. I think it works when the browser has all the images already loaded in the cache.

I get the same error message in the console using both browsers.

Now I know I'm not the only one with this problem :). Is there anything wrong in this version of Mono? Can we do anything to solve this error? Any help is appreciated :).

Thanks!

Have the same problem... I think that problem is in thread safety... Tracks lead to _wapi_send call at mono/mono/metadata/socket-io.c. Definitely exception raises in native code. And i think it's nothing special about Mono 2.4.2... I looked through sources and all of them (spoted) are same in both versions. My tests shown that sometimes it xsp crashes because of loading js, and even because of contineous-Ctrl-F5 of an empty html (like ); But if to laod pages with higher interval the probability of crash lowers...

It has been fixed and it will be featured in version 2.6.5:
