Datablade 3.3 and NS Enterprise 3.5.1 problem

We have an Alpha Server 1200 with OSF1 4.0d and we are trying to configure Datablade 3.3 with Enterprise Server 3.5.1. Several configuration lines must be included in Enterprise config file (obj.conf). But lines doesn't work properly, we obtain following error: Internal AIO consistency error: Cannot use libaio_raw with threads. Either relink without -pthread or link -laio, not -laio_raw. Aborting... exception system: exiting due to multiple internal errors: exception dispatch or unwind stuck in infinite loop exception dispatch or unwind stuck in infinite loop server exit: status 1 and Enterprise isn't launched. If we delete those lines and Enterprirse runs properly. Anyone know a solution ? TIA Eduardo Quintas OTRI - Universidade da Coru'a.
