An electronic apparatus comprises: a memory that stores at least one instruction corresponding to at least one program; and at least one processor, comprising processing circuitry, electrically connected to the memory, wherein at least one processor, individually and/or collectively, is configured to execute the at least one instruction as a process, and to: acquire performance information of the electronic apparatus and an amount of available memory; determine a memory threshold value based on the performance information and the amount of available memory; update a memory threshold value to the determined memory threshold value; and based on the amount of available memory being less than the memory threshold value at a certain point in time, terminate a certain process. ## Claims ### Claim 1 An electronic device, comprising: a memory storing at least one instruction corresponding to at least one program;
