Problem Note 43126: CPU time limit set via ulimit -t is ignored
 |  |  |  |  |
In UNIX environments, ulimit -t is used to set the maxiumum CPU time that can be used by a process. If that time limit is exceeded, the operating system sends the SIGXCPU signal to the process, which then ends.
SAS® does not handle the SIGXCPU signal, so if you use ulimit -t to limit the amount of CPU time a batch SAS process can use, that limit is ignored and the process continues to run.
