Informix 7.12 and HP 10.01

We had to back off from version 7.12 for two reasons, the first which we fixed, the second which we haven't been able to overcome. The cdrom runtime and development version 7.12uc1 contain a bug in the install process which caused programs using shared libraries to fail. The fix was to 'brand' libgen.sl manually. "How did that get by QA?" one might ask, not testing the simple stuff like a compile, perhaps? The second involved repeated -242/-113 errors on spx connections when we try to drop a temp table. We also encountered phantom/orphaned sessions. Informix, as usual, it seems, when the problem isn't straight forward is of little help. Their tech support is hampered by too few tools, if any, to allow them to trace or even dump their system (for crying out loud) on hp's. I have also been severely disappointed and repeatedly burned by their apparently inept quality assurance (i.e 7.10UD1, 7.12UC1, bad fixes to name a few). The bight spot, at least, is after much pain we are currently running version 7.11UC2 and that seems more stable - much to everyone's relief. Because we had to back off there is very little likelihood that this problem will be resolved because they can't capture it on our system or recreate it on theirs. Jeez.
