In other way, I would say, that it was due to oracle's laziness. Check this scenario: Lately my 8.1.6.3 DB's MTS started to dump its servers and dispatchers frequently on my solaris system. This was giving me ORA-6000 with some 16.... So I went ahead and opend a TAR with oracle support. It took the support almost 3-4 weeks to find the cause. It seems that this was a known problem with the HP but not with the Solaris. Then their development group came up with a reply, that this could be due to the bug 1603274. and they had fixed it on 8.1.7. Since I haven't migrated to 8.1.7, I don't know how far it works on Rel 3.
