WinSyslog Event ID 11187: A configured input service type is not recognized#

Answer#

The configuration contains an input-service type that the installed product build cannot create. The product ignores that service object and continues loading the remaining services.

Event details#

Event ID: 11187
Severity: Error
Component: Service configuration
Windows Event Log source: AdisconWinSyslog
Available since: 26.07
Message pattern: Unknown service type {service_type} was found and ignored.

Possible causes#

The configuration came from a newer or incompatible product version.
A manual configuration edit supplied an invalid service type.
The service object is incomplete or damaged.

Immediate checks#

Export and back up the current configuration.
Identify the ignored service and compare its type with services supported by the installed product version.
Recreate it with a supported type or install the intended compatible version, then reload.

Detailed procedures#

Validate configuration and reload it safely — Back up, inspect, correct, and test the exact invalid configuration object.
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#

Confirm that the recreated input service starts and receives a controlled event without Event ID 11187.

Evidence to collect#

The complete Windows Application Event Log entry and neighboring product events from the same time window.
The exact product version, affected service or action name, and event timestamp with time zone.
The affected configuration object and a bounded debug log covering one controlled reproduction.
Remove passwords, tokens, license data, private keys, message payloads, personal data, and customer-identifying names, addresses, hostnames, domains, and network addresses before sharing evidence.

Escalation#

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