This problem seems to be only present when using an empty suffix. I wasn't able to reproduce it with a non-empty suffix at least.
It seems to be a problem with the idlcache. After setting "idlcachesize" to 0 the problem went a way for me. And yes, it seems to have been in the RE24 tree for a longer time already (2.4.12 was affected as well). -- Ralf
