Problem Note 59983: Retrieving more than a million records using SAS/ACCESS® Interface to the PI System under UNIX returns a segmentation violation error
 |  |  |  |  |
When you run SAS/ACCESS Interface to the PI System on Linux or UNIX operating systems, you might get a segmentation violation error similar to the one shown below:
Please contact technical support and provide them with the following traceback
information:
The SAS task name is [DATASTEP]
Segmentation Violation
You see this error when you are trying to retrieve more than a million PI Point (tag) records using the PISYSTEM engine.
Note: The number of records you try to retrieve before you encounter this problem varies depending on your available system memory.
The problem occurs because SAS/ACCESS Interface to the PI System calls PI Web API to retrieve data from a PI server when it runs on Linux or UNIX. The problem is caused by a memory leak in the PI Web API, which is fixed in SAS® 9.4 TS1M5. You do not encounter this problem when you run SAS/ACCESS Interface to the PI System under Windows, because it calls PI SDK API instead of PI Web API.
