CAUSE:
The hostname on Linux is limited to 255 bytes. Progress uses a C function called "gethostname" to determine a UNIX machine"s hostname. If the hostname is longer than 28 characters Linux returns a null string to Progress, as opposed to a truncated name. The gethostname function returns the correct hostname value, however the return code is a -1 which means that the gethostname function failed. The -1 return code results in Progress setting the hostname in the .lk file to nulls rather than the value returned by the gethostname function. Since a nul string is returned in the low level functions, this is part of the reason for the remaining .lk files and in some instances, zombie shared-memory segments pids have been known to occur.
FIX:
The full hostname must be less or equal to 28 characters on Linux.
To determine the length of the current hostname, run the 'hostname | wc -m' command at the UNIX shell prompt.
To change the name of the Linux hostname, type 'hostname <newhostname>' (where <newhostname> is 28 characters or less).
This operation will require ROOT permission. An alias (for the long) hostname can be created in /etc/hosts of "yphosts" (if NIS is used).
