请教高手！informix online 出现错误代码-271

crc001

-271    Could not insert new row into the table.

This problem has many possible causes, including a locked table or a full disk. Check the accompanying ISAM error code for more
information.

经查不是full disk也不是locked table,实在想不出还有什么原因，请高手赐教！
还有不知哪位有 ISAM error code ，，，thx!
