Problem Note 60456: Using memory-based libraries might cause a wrong page to be returned or the data set to appear in the wrong library
 |  |  |  |  |
Problems might sporadically occur when you are using memory-based libraries.
Problem 1
Concurrent SAS® sessions that use memory-based libraries might produce a SAS I/O error similar to the following:
ERROR: Expecting page 22, got page 9 instead.
ERROR: Page validation error while reading WORK.SASMAC1.CATALOG.
ERROR: File WORK.SASMAC1.CATALOG is damaged. I/O processing did not complete.
ERROR: The SAS Macro Facility has encountered an I/O error. Canceling submitted statements.
ERROR: Page validation error while reading WORK.SASMAC1.CATALOG.
ERROR: File WORK.SASMAC1.CATALOG is damaged. I/O processing did not complete.
ERROR: The SAS Macro Facility has encountered an I/O error. Canceling submitted statements.
Problem 2
A similar problem might occur when using memory-based libraries with multiple libraries in a single SAS session. This problem does not produce an error. Here are some symptoms of this problem:
-
Data sets that reside in one library appear to be in a different library.
- The original data sets associated with the memory-based library appear to be missing.

If memory-based libraries are used with heavy I/O with multiple libraries or many concurrent SAS® sessions, random page errors might cause a step to fail.
