Allan, Thanks for the information. It's very useful for us to understand the constraints that you're working with on your end. Is there a deadline by which these AIX systems must be upgraded, or can you get a temporary exception for operational systems? I'll be so bold as to speak for others here, but our intention is to address this issue as quickly as possible. I also understand the concerns about being one deep on LDM relay systems (tgsv50/51) and didn't know if you had operational issues with that as well? Finally, I'd like to accept your offer of a test AIX system. Let us know when the system is available! mike On Mar 25, 8:05am, Allan.Darling wrote: > Subject: Re: tgsv50 and AIX patch info > > Mike, > > Thank you (and all the other Unidata staffers who have worked on this issue) > for your investigation on the AIX upgrade issues that have negatively > affected LDM.
