uhm,

- the strace line was just my fault, I was trying running as root on the command line
- when I retried with user xrootd, I get instead the lines below, which terminate with a segv (*)

so the last message is consistent with the one in the logs:

Ciao, I am trying to upgrade one of the CMS EU redirectors from 3.3.6 to
4.2.2 (with no configuration changed at first approx)

The problem is that the main cmsd seems to die soon after start. No real
message in the logs, but with strace I see a very suspect

writev(2, [{"Copr.  2007 Stanford University/"..., 42}, {"\n", 1}], 2) = 43
geteuid()                               = 0
gettid()                                = 53572
writev(2, [{"150824 09:47:27 53572 ", 22}, {"Config", 6}, {": ", 2},
{"Security reasons prohibit cmsd r"..., 73}, {"\n", 1}], 5) = 104

 Well, that line ought to end up either on STDERR somewhere or in some log file. Alternatively, suggest "strace -s 1024" to get the full error message..

Cheers
jan
