SAS Batch Jobs Intermittently Failing

344 Views Asked by At

We have a high volume of SAS batch jobs that are run using a scheduling/polling tool called VisualCron. Say 100+ VisualCron instances (one each for each of our customers) calls a VBScript file that polls an SQL "jobs" table and identifies the work queue.

For each VisualCron instance, we have BAT files that call the SAS programs via SAS.EXE, such as:

sas.exe -sysin "sasprogram.sas" -log "somelogfile.log" -config "I:\Program Files\SAS\SASFoundation\9.2\nls\1d\SASV9.CFG"

I believe, under high load, we intermittently see jobs failing. The Windows Event Viewer Application log shows the following errors - but I'm unable to search on Google for what these really mean and why/when they occur. Any one have any experience around what these could be?
