Startup parameter: usealtsignalstack

Startup parameters change the behavior of the HPE Service Manager server. You can always set a startup parameter from the server's operating system command prompt.

Parameter

usealtsignalstack

Description

By default, the Service Manager processes register the alternate signal handler to handle signals generated by the operating system. When usealtsignalstack is enabled, the processes handle stack overflow exceptions properly. The signal is delivered on an alternate stack, and the process has a chance to terminate the offending thread and continue to requests of other threads that exist on the process. Older Linux kernels may not honor the alternate signal stack. If you are running on older Linux kernels, disable this feature.

Note This parameter applies to UNIX only.
