Intermittant failures in eckit_test_container_sharedmemarray about eckit

Does anyone have any ideas for this? I have googled it but the suggestions seem to involve kernel settings that require root access that I don't have.

@tlmquintino would you know?

There is a limit on the number of semaphores one can allocate in user land.
The semaphore limit is probably reached on that system, for the user running the tests. This may happen for multiple reasons, including previous tests failing before cleaning the semaphores.
These tests need a few semaphores to work, so one way is for the user to cleanup its semaphores before starting the tests (this has to be done outside the ctest environment).
In Linux, this can be done with the command ipcrm

[tlmquintino]

something like:
for sem in $(ipcs -s | awk '{print $2}'); do ipcrm -s $sem; done

Thanks, I've arranged for this to be addressed in the test environment.
