Does the rsa.o file exist in that folder? And is it of size zero, or larger? If you delete it and recompile (should take only moments), does it work?
Sometimes the compilation fails for some reason or another, and the produced file is incomplete or even zero-size, deleting it and recompiling fixes that.
The more I think about your issue, the more I have a suspicion that your storage medium is failing, slowly. One corrupt bit and it's bye-bye to a functioning server.
