HP-UX/Informix 7.3

Currently, we are developing a OLTP application on HP-UX 10.20 using Informix 7.23.UC7. Since we still have time prior to deployment we are thinking of migrating to 7.3 to take advantage of the improvements added in this release. I would like to know if any other HP-UX sites are running release 7.3 and if you would recommend it for production usage. I know it has not had much burn-in time but I do not have confidence in release 7.23.UC7. When we originally upgraded we received release 7.24.UC3 which, if you do not already know, was put on quality hold. Informix then shipped us a down-grade (7.23.UC7) as its replacement. Consequently, it does not feel to good having a release with know bugs floating around just waiting to bite. In fact I have an open case with technical support that deals with the engine dynamically allocating shared memory segments (21 to be exact) in the middle of the night when absolutely nothing was going on! Thanks In Advance, Mark
