This counts SCTP associations that terminated abruptly via the ABORT primitive from any prior state, representing ungraceful terminations rather than the clean SHUTDOWN handshake tracked by cSctpShutdowns. A rising rate of aborts on this device is a strong signal of underlying instability - such as a misbehaving peer, a security device injecting resets, or a software bug - rather than normal application-driven connection teardown. If this spikes at the same time customers report dropped signaling sessions, that timing correlation points investigators toward whatever changed in the path around that spike.
