Looking more closely, it gets worse -

It looks as if your filesystem was unable to meet the demand for a file autoextend (even though it was quite a small file)

It is interesting that 'create intermedia index' generates so much rollback - the 'extensibility option' isn't quite as transparent as one might hope - 'create index' for normal data doesn't require very much rollback at all.

I haven't used the context option since 7.3, but there was some ctxsys parameter that could be used to change the amount of memory allocated for building context indexes - if this is still possible for Intermedia then a larger in-memory build might reduce the amount of rollback generated on the build, since I guess the rollback appears from updates as index sections are merged.

Also, is there a 'nologging' option with intermedia index build ? For normal data, this is irrelevant for rollback purposes, but perhaps for intermedia it would have some side-effect on rollback.
