The SNMP subagent encountered an error attempting to set up the signal handler for the signal specified by signal. reason is the error returned by the C runtime library for the failing sigaction() call. If the signal handler is not correctly enabled, the subagent will continue processing, but certain functions controlled by the failing signal will not function properly. Functions controlled by the signals are:

SIGABND

Handler controls error reporting and cleanup functions when an abend occurs. If sigaction fails for SIGABND and an abend occurs, trace information about the abend will be lost and certain resources might not be properly cleaned up. The subagent might not be automatically restarted.

SIGTERM

handler controls cleanup of resources during termination. If sigaction fails for SIGTERM, the subagent will not be automatically restarted when a SIGTERM is received.

SIGPIPE

handler allows the subagent to detect when the connection to the SNMP agent was terminated by the agent (for example, if the agent times out while waiting for the subagent response and closes the connection). If sigaction fails for SIGPIPE, subagent might either hang or terminate without restart.
