Samuel or David,
Could you apply this follow-up fix so that it can be backported along
with the offending commit (which was just added to the stable queues)?
We would only hit this error path if an ida allocation fails due to OOM;
so while this is not critical, it would still be nice to get it fixed.
Thanks,
Johan
