    • A method for determining a suspect memory leak, including: sampling the throughput and memory usage of an application server; based on the sampled throughput, monitoring whether the throughput decrease continually, and based on the sampled memory usage, monitoring whether the memory usage remains stable within a predefined range; in response to a continual decrease of the throughput and the memory usage remaining stable within the predetermined range, determining that the application server is suspected of having a memory leak. Using the solution of the present invention can free an administrator of the burden of artificially identifying suspect servers, can identify a suspect server during runtime and further determine whether it actually has a memory leak.

    • The embodiments of the present invention disclose a backplane and backplane system. The backplane includes at least two service slots with the same function and an exchange slot. Among the pins of different service slots with the same function respectively connected to the exchange slot, at least two pins are arranged to resemble a stepped form. When arranged in this manner, the distribution and orientation of the connection lines connecting the pins of the service slots with the same function to the exchange slot may be adjusted, and wiring density within a single wiring layer may be increased, which therefore enables the connection lines between the service slots and the exchange slot to be staggered from each other in less wiring layers or even one wiring layer, and as a result, decreases the number of the wiring layers to be used, and reduces the costs of the backplane.
