[Mono-aspnet-list] Cannot load symbols from resource files: is it a bug?

[Antonio Anzivino]

Hello,

I'm trying to debug my web application under Linux using mdb to search for a
possible Mono deadlock (at least, as it just hangs, it looks like that, and
my app is not subject to deadlocks).

 

I ran a stand-alone mod-mono-server2 instance as my user and it's connected
to Apache via Unix socket. After some hours, the application (finally)
hanged and I tried to attach mdb. I found this:

 

Cannot read DWARF debugging info from symbol file

/usr/src/packages/BUILD/mono-debugger-2.6/backend/os/Bfd.cs:569 

The Mono runtime of the target application does not support attaching,

attaching as a native application.

 

 

That's a resource file. No debug symbol is expected to be there!

Should I ignore it or is it a bug with the debugger?

 

Thank you
