In Red Hat Enterprise Linux (RHEL) 6, the default value for the maximum number of processes (nproc) was decreased to 1024. If the maximum number of processes is too low, then the SAS^® Deployment Wizard might fail, most typically at the stage where it starts the web application server. This behavior is more likely to occur when SAS web applications are deployed to multiple web application servers (for example, SASServer1, SASServer2, SASServer8, and so on).

If the SAS Deployment Wizard fails while it is starting a server, check the web-application server log for an error similar to the following:

You might also see the following error appears in the Remote Services log:

If you encounter either of these errors, check the user limit for maximum number of processes. The SAS Deployment Wizard uses the soft limit. SAS recommends setting the maximum number of processes (soft limit) to at least 10240.

If the user limit for nproc is too low, the SAS® Deployment Wizard fails when you try to start a web application server. You might see an out-of-memory error with a message about failure to create a new thread. This message can indicate a need to increase the maximum number of processes.
