Signals Used With Resource Controls

For each threshold value that is placed on a resource control, the following restricted set of signals is available:

SIGBART

Terminate the process.

SIGXRES

Signal generated by resource control facility when the resource control limit is exceeded.

SIGHUP

When carrier drops on an open line, the process group that controls the terminal is sent a hangup signal, SIGHUP.

SIGSTOP

Job control signal. Stop the process. Stop signal not from terminal.

SIGTERM

Terminate the process. Termination signal sent by software.

SIGKILL

Terminate the process. Kill the program.

SIGXFSX

Terminate the process. File size limit exceeded. Available only to resource controls with the RCTL_GLOBAL_FILE_SIZE property.

SIGXCPU

Terminate the process. CPU time limit exceeded. Available only to resource controls with the RCTL_GLOBAL_CPUTIME property.

Other signals might be permitted due to global properties of a specific control.

Calls to setrctl() with illegal signals fail.
