Got error 139 from storage engine (1 reply)

I have an InnoDB table that has a text field, longblob, a few bigint unsigned fields, and a varchar(128) that has been in our database for some time now. All of a sudden I am getting the following error when I try to select the logblob field in one of the rows:

ERROR 1030 (HY000): Got error 139 from storage engine

Any help would be greatly appreciated.
