[Freeswitch-users] mod_managed.so Loading error: mono_class_from_name undefind symbol

HI All, When we trying to load mod_managed.so in CentOS, We are facing a issue, *mono_class_from_name undefind symbol.* ** mono2.8.1 we are using for this. ** Prevously we got mono_thread_attach error in runtime, we commented the mono_thread_attach in mod_managed.cpp then we are facing the above error. Any Idea? Thanks-- Srinivasula Reddy K
