Dear DBAs

I have a tablespace for index with 5 file with different size from 500mb - 2000 mb.

Total tablespace size is 6g and used 5317mb abote 86.13% usage.

I got the error today.
ora-1654 unable to extend indx sechma.indexname by 256 in tablespace tablespacename.

The following is the query I got for the tablespace .

We can see the index takes 92 extents and maxextends setting is 8192. I then set autoextend on a datafile then error is gone.

What is the reason to cause ora-1654 even there are 700mb space avai. I also checked the tablespace and index setting with both have next extend 1024k, maxextend 8092.
