I had the similar issue. Patch will indicate there are few empty files. I fixed it by adding back server and daemon and then lmgrd the server. There are people had the related problem, but I didn't get this message, I guess your issue are the same as mine. So I am not sure if this is the cause.
ERROR: Current execution environment is VCO=aoi. Software tree is for environment VCO=ixl.
They use the following line to fix it.
setenv CALIBRE_2013_4_ALLOW_IXL_ON_RHEL6 101010
这是怎么回事 license不行吗
