stopped while creating index.

[Tom]

Hey, all.

Hardware: Itiaum 2 with 1.3G cpu * 4 and 8G RAM.
OS: Red Hat Enterprise Advanced Server 3.0
Mysql: mysql-standard-4.0.24-gnu-ia64-glibc23

I created a index on a large table with more than 100,000,000 records by the 
following command.
mysql> create index scn_ra on twomass_scn (ra);

It went good within 20 hours although it costs nearly 8G RAM. Then it stopped 
and the err log say Warning: Enabling keys got errno 116, retrying. It has not 
gone on by now.
I cannot figure out why and I really appreciate any suggestion.

Thanks.



Eswine.
