1. The program on high-performance hardware deployment strategy
For example: using a plurality of 64-bit and 32-bit jdk VMs
2. Inter-cluster synchronization causes memory overflow
When the network can not meet the transmission requirements: e.g.
3. heap overflow error caused by external memory
In addition to the generation of Java heap and eternal life, there are other areas will take up more memory Direct Memory
4. External command causes slow system
For example:. Runtime.getRuntime () exec () the cloning process and then exit process
The JVM server process crashes
For example: The other system services a web speed of more and more unequal waiting thread with a message queue
6. The data structure resulting in inappropriate conduction large memory footprint
7. A long pause caused by the Windows virtual memory
