Ouch sorry to hear about all of your problems - and I've had some as well with 11.2, but nothing so severe. It seems like every update recently has caused some new problem, requiring a clean install.
I don't know, but it certain feels like something is. It feels like the update cadence increased significantly with 11.2 so I looked the updates and their release dates to see if anything could be discerned:
- 11.2-RELEASE - 11.2-U.2.1 = Average days between updates = 21 days.
- 11.2 RELEASE - 11.2-U4 = If the 11.2-U3 & 11.2-U4 targets are met, average days between updates = 19.5 days
- 11.1-RELEASE - 11.1-u7 = Average days between updates = 45.2
- 11.1-RELEASE - 11.1-u8 = If the 11.1-U8 target is met, average days between updates - 49.5.
I don't know that there is really a story to be told here, but two opinions: (1) It seems like the current update cadence for 11.2 is quite brisk for this type of software, and (2) I'd much prefer having to deal with updates less often as with 11.1.
I suppose that 11.2 did bring a number of new feature updates so more frequent updates are to be expected?
But the last update, U2.1, was a hotfix to address 2 regressions. Considering that fact and with 11.3-BETA1 due in 16 days, I wonder if there is contention for resources and which is negatively affecting 11.2 maintenance?
[likely trying to connect dots where there is no causality though]
