Problem Note 64207: A segmentation violation occurs after you submit SYSTASK and WAITFOR statements repeatedly within a macro loop
 |  |  |  |  |
You might encounter a segmentation violation after you submit multiple SYSTASK and WAITFOR statements under the following conditions:
- You submit several SYSTASK statements.
- You also submit several WAITFOR statements that list all of the previous SYSTASK tasks.
- You repeat the above actions, typically through macro programming logic.
- These statements run on an operating system based on UNIX.
After the segmentation violation occurs, the SAS® log shows traceback information that looks similar to the following:
ERROR: An exception has been encountered.
Please contact technical support and provide them with the following traceback information:
The SAS task name is [Program ]
Segmentation Violation
