What are the different “Transient error handling” properties of your trigger ?

You may have a “Retry Until” to “Succesfull” and your processing services always fails and processes the same document again and again.

Or “suspend on error” to true

Hi RGJ,

There are two issues:

1. trigger client queue is increasing - if processing sequence of the document is not important (documents can be processed in any order), you should change trigger processing mode to concurrent. It will help in processing documents at faster rate.
2. service is getting hung - There could be resource/pipeline related issues which leading to service getting hung and should be investigated. If this issue is not resolved, even making trigger processing mode to concurrent will have those many threads going into hung.

I suspect that this has nothing to do with the trigger configuration. It is likely that the problem is in the trigger service–it is hanging or crashing. Debug that first.

This isn’t 8.0 or 8.2 is it? There was a bug whereby triggers ended up disabled. There’s a SAG fix for it available… Should be able to work out whether it is the cause as the trigger will be disabled.
