TranslationException: “Connection pool shut down” during Microsoft Machine Translation

com.adobe.cq.wcm.translation.impl.CQPageMachineTranslator Error while translating property

com.adobe.granite.translation.api.TranslationException: Error Code: TRANSLATION_FAILED. Message: java.lang.IllegalStateException: Connection pool shut down

at com.adobe.granite.translation.connector.msft.core.impl.MicrosoftTranslationServiceImpl.getTranslatedTextForArray(MicrosoftTranslationServiceImpl.java:549)

Microsoft Bundle restart resolves this but it is happening frequently.

Hi @Abhilasha_S.,

1. Increase HTTP Connection Pool Size

Go to:

OSGi -> com.adobe.cq.wcm.translation.impl.MachineTranslationConfigProvider

Update:

• Max Connections -> 100

• Max Connections per Route -> 50

• Request Timeout -> 30s+

• Socket Timeout -> 30–60s

(Default values are too small for real translation workloads.)

2. Check Microsoft Translation OSGi Config

OSGi -> com.adobe.granite.translation.connector.msft.core.impl.MicrosoftTranslationServiceImpl

Ensure:

• API Key + Endpoint are correct

• Timeout values are not too small

• Retry count is enabled (set to 3)

3. Reduce Parallelism in Translation Workflows

Path:

/libs/settings/workflow/models/translation/prepare_translation_project/jcr:content

or if overlayed:

/conf/global/settings/workflow/models/...

Reduce:

• maxParallelJobs

• Split large translation jobs into smaller batch launches (10–20 pages)

@Abhilasha_S - Looking at the error and the fact that a Microsoft bundle restart fixes it temporarily, this seems more like a connector stability issue than a content or workflow problem. Applying the tuning changes is a good starting point. If the issue still repeats, we should monitor the pattern and raise it with Adobe Support, as this is usually resolved at the connector or platform level.
