■ Causes
When it is not possible to ensure the memory allocation value (Heap size) that is set in DataSpiderServer.lax, this error occurs. Check the help in Reference Information for memory allocation value (Heap size).
And, the memory allocation value (Heap size) that can be set varies with the difference in the used OS. Check the following for details.
- In case of 32bit
In case of 32bit, as per the specification the upper limit of the memory allocation value that can be set is 2GB. However, the memory that can be allocated for process is controlled by OS. Hence, 1.0 ~ 1.6GB will be the value which can be specified actually.
- In case of 64 bit
Unlike 32bit, as per the specification, in 64bit there is no upper limit in the memory allocation value (Heap size) that can be set. Though you can set up to the maximum value of the actual physical memory, since the memory is used even by OS or other applications, configure after checking the memory capacity that can be set
* Either it is 32bit or 64bit, the maximum value that can be set varies with the environment (Memory Capacity). Test some of the settings and set the value that can be ensured in the operation.
