[systemd-devel] Cannot add dependency job for unit... Cannot allocate memory

[Anthony Messina]

I'm not sure if this is the right place to ask, so please direct me to the 
proper list if it's not.  And byt the way, THANK YOU for systemd!  The more I 
read and try, the simpler my systems get.

Anyway, I'm writing due to an issue I'm seeing on a few of my Fedora 18 
machines after I've created a unit file for instantiation that will acquire 
Kerberos tickets for user-based services such as apache and mythtv, etc. to 
access NFSv4.1 filesystems.  Any assistance would be appreciated, especially 
with pointers on improving the unit file itself.  I have attached the dmesg 
output after booting with "systemd.log_level=debug systemd.log_target=kmsg"

Thanks in advance -A

I am intermittently running into the error:
"Cannot add dependency job for unit k5start at mythtv.service, ignoring: Unit 
k5start at mythtv.service failed to load: Cannot allocate memory. See system logs 
and 'systemctl status k5start at mythtv.service'
 for details."

And systemctl status k5start at mythtv.service shows
k5start at mythtv.service - k5start Kerberos ticket service for mythtv
          Loaded: error (Reason: Cannot allocate memory)
          Active: inactive (dead)
            Docs: man:k5start(1)

This issue does not happen every time the computer is started, but the success 
is about 50/50.  However, if I reload systemd and try to start the unit, it 
works every time.

# systemctl --system daemon-reload
# systemctl start k5start at mythtv.service
# systemctl status k5start at mythtv.service

The unit file is below (I've only wrapped the lines for email purposes) and I 
have instantiated the unit by "systemctl enable k5start at mythtv.service".
