A method includes first determining whether a character string related to a specific type, from among types of a plurality of files, is included in attribute information of each of the plurality of files which a process that is being executed refers to or updates, second determining the types of each of the plurality of files using higher priority which is given to a first file than a second file from among the plurality of files, the first file having a first attribute information which includes the character string, the second file having a second attribute information which does not include the character string, and outputting a determination result regarding the types related to the plurality of files.

A computer-readable recording medium stores a program for causing an apparatus to execute an address managing process including: associating information that identifies a branch destination routine of a branch instruction with a jump instruction in which a relative address to the branch destination routine, and generating the associated information and jump instruction in a branch destination management entry on a memory; setting a relative address to a position of the jump instruction that corresponds to the information that identifies the branch destination routine of the branch instruction, as a branch destination relative address of the branch instruction; and changing the jump destination of the jump instruction that corresponds to the information that identifies the branch destination routine, to a relative address to a position of the branch destination routine of the movement destination, with reference to the branch destination management entry when the branch destination routine is moved.

A memory leak detecting method includes: producing an object which occupies an area on a first area of the memory; checking a presence of a pointer which points at the object separately so as to remove the object and to repeatedly carry out a process for increasing a counter value of the object; moving the object from the area on the first area of the memory to an area on the second area of the memory when the counter value exceeding a first threshold; and moving the object from the area on the second area to the area on the first area and clearing the counter value of the object upon the object occupying the area on the second area.

Operation processing device and method of detecting memory leak

A recovery virtual machine acquires execution frequency information from a file, and converts a procedure, of which execution frequency is high in the execution frequency information acquired, to native code, and the time for starting the conversion is thereby reduced. Furthermore, by performing conversion at a timing at which a target procedure is invoked, load occurring due to the conversion is distributed, to prevent occurrence of failure in execution of an application caused by the load occurring due to the conversion.
