Hi,
these behavour should only occur if some part of domino (perhaps the whole server) had crashed before.
Than it is possible that due to some "zombie" processes shared memory cannot be written. A clean reboot
of the linux machine should fix the problem.
For a look at the system wide ressources you can use the ipc-tools
ipcs and ipcrm.
ipcs will show Semaphores, Message Quese and Shared Memory regions, ipcrm will remove ressources.
Perhaps stopping domino and removing all system wide recources for the domino-user (typically notes)
will also fix your problem too.
Greetings Hans-Georg
