Adapter fails to start showing a status of "Starting up" in the Administrator
If the process ID "-1" is allocated to the Adapter process, then this indicates some error launching the Adapter. This error is generally a library dependency. The following are the known errors:
Case 1: Error while loading shared libraries: librfccm.so: wrong ELF class: ELFCLASS64
Case 2: Error while loading shared libraries: librfccm.so: wrong ELF class: ELFCLASS32
Case 3: Similar issues have been observed for the following libraries
libresolv.so.2 sunw_2.2.2
libstdc++-libc6.2-2.so.3

Errors are sometimes observed due to missing dll files in the SysWOW64 folder of the Windows machine.
