INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10

The internal function within IDS known as btusearch() will
search an index fragment from the root to locate a given item.
The search will traverse the levels of the btree and leaf pages
within a level to locate the key value and rowid. Depending on
how the function is called the pages may be checked as
candidates for page split or merge operations, each of which
could result in pages being written to the physical log.

Index maintenance operations such as the sysadmin task "fragment
repack" may result in large numbers of pages being physically
logged as the index is repacked. Checkpoints will be triggered
if necessary as the physical log fills but if the level of
system activity is such that there are a number of such
operations running concurrently then a situation may arise when
the physical log fills completely. This will result in an Assert
Failure: Physical log file overflow and the IDS server will need
to be restarted.
