IT27018

With variable row length and MAX_FILL_DATA_PAGES pages might forever offer room that never satisfies any new row, potentially causing long checkpoint blocks

IT27262

onmode -- output shows the wrong usage syntax for onmode -I

IT27265

Function Replace prints different results for the same record which has char variable.

onstat -z can hang the server if it finds a bad mutex

IT28303

jdbc client that retrieves auto generated keys for insert into ... select from ... statement leaks opentable memory and open table entries in IDS

IT29239

spurious and permanent error -106 (non-exclusive access) possible

IT29322

When rtree node splits and server has hdr/rss configured, then pages on hdr/rss get out of sync with primary due to slot length difference
