WinSyslog Event ID 11085: Heartbeat service: heartbeat operation raised an unknown exception#

Answer#

Heartbeat service: heartbeat operation raised an unknown exception. The product recorded this while processing heartbeat service; the appended event detail identifies the affected object, operation, or provider error.

Event details#

Event ID: 11085
Severity: Error
Component: Heartbeat service
Windows Event Log source: AdisconWinSyslog
Available since: 26.07
Message pattern: Heartbeat service: heartbeat operation raised an unknown exception. Additional detail: {event_detail}

Possible causes#

The product service, dependency, service account, or required Windows resource is unavailable or incorrectly configured.
Windows returned the appended startup, shutdown, permission, timeout, or resource error.

Immediate checks#

Record the affected service or component, service account, state, dependencies, and complete runtime detail.
Check recent Service Control Manager and neighboring product events for the first failure.
Correct the specific dependency, account, permission, or resource condition and perform one controlled retry.

Detailed procedures#

Verify sender, receiver, and queued-message recovery — Prove end-to-end recovery and backlog drainage.
Collect an Event ID and neighboring product events — Preserve the complete event and the product events immediately before and after it.
Export configuration and collect a bounded debug log — Create a text configuration export and time-bounded debug capture, then disable debugging.

Verify the result#

Repeat or monitor the affected operation and confirm that Event ID 11085 does not recur and that heartbeat service processing continues.

Evidence to collect#

The complete Windows Application Event Log entry, including all event detail.
The product name, exact version, service account, and event timestamp with time zone.
A configuration export and debug log covering the same time window, with secrets removed.

Escalation#

If the event continues after the detailed procedures, collect the listed evidence and contact Adiscon Support.
