call stack missing info on mono with apache and mod_mono
I had the same problem. There are quite few solutions. First of all, you MUST install mono-core-debuginfo package, or it might not work.
Second, you must run Mono in debug mode
*Solution 1:Add this to your virtual host section/httpd.conf
MonoSetEnv MonoDebug true
*Solution 2:Start xsp/mod-mono-server with debug
$ MONO_OPTIONS=--debug xsp2
