53952 - Portfolio pricing fails with message, "Segmentation Violation In Task [ RISK ]"

Problem Note 53952: Portfolio pricing fails with message, "Segmentation Violation In Task [ RISK ]"

When you run a risk analysis project in SAS^® Risk Dimensions^®, the project might fail while pricing the portfolio. The following message is reported in the SAS log:

Segmentation Violation In Task [ RISK ]

This issue is known to occur on the PowerPC architecture on the AIX operating system when a method contains a large number of SAS statements. The large number is likely tens of thousands or more. There is a hardware limitation that can prevent SAS from traversing a large number of the lines of source code that are generated while executing the SAS statements.

The workaround is to sufficiently reduce the number of SAS statements used in the method. Due to the nature of how the lines of source code are generated, it is not possible to estimate the maximum number of SAS statements that can be used. However, in one test case, this issue occurred when using 140,000 SAS statements in a single method.

Note that the "Segmentation Violation In Task [ RISK ]" message is generic and is not necessarily caused by this issue. To help verify whether you have encountered this particular cause, you can test by replicating and running the risk analysis project in a different operating environment.

For additional guidance to troubleshoot other possible causes of the "Segmentation Violation In Task [ RISK ]" message, see Troubleshooting SAS® Risk Dimensions®.

Many SAS statements inside a single method is one of several possible causes of the error message, "Segmentation Violation In Task [ RISK ]", when you run a PROC RISK step.
