$ Server
/usr/lib/hpux64/dld.so: Mmap failed for the library : Permission denied.
Killed

Resolution

The cause is the missing execute permission by the user of the library. If you have changed from default permission (rwxrwxr-x), please put it back to the value by:

$ chmod 775 <$VBROKEDIR>/lib/liborb64_r.so

This exception may not occur on other UNIX platforms.
