Anybody run into the following issue with their OAM database? Sadly, due to circumstances out of our control, we are way out of support on both CMOD and DB2 so we have no help from IBM forthcoming. Shot in the dark that someone else has run into this.
We have an instance that is loading a lot of PDFs through a windows loader into our CMOD instance on z/OS. Everything is going fine until, after only a few weeks and only a few million documents, we hit this:

Our DBAs are very inexperienced and have been unable to diagnose the issue. Our solution was to create a new OAM database which, as mentioned, only lasted a couple weeks and now we find ourselves with the same issue. Available storage is way more than needed so were having a hard time figuring out why OAM cannot find enough available segment space. We have a half dozen other instances on our system that have been loading this way for years with no issues. If anybody has run into something similar I would appreciate it if you could share your findings.
