MaxListenersExceededWarning in aggregation-service.log

Hello, I'm seeing from time to time a message like the following in the aggregation-service.log:

 

2020-12-09 09:00:55: (node:31020) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 close listeners added. Use emitter.setMaxListeners() to increase limit

 

Not sure how critical this is but how do I go about increasing the limit?

 

Thanks

Hello Matt,

 

This error is a known issue, please try to install latest patch on the Prognosis servers if it is not installed. If after the install the error is still happening, please log a support case with the diagnostic data, eg irfax, Sfbfacts, we will investigate the issue. 

 

Thanks

David

Hi David,

 

I'm on 11.8P3 so I have the latest patch available.  I was just wondering if there was a setting that needed to be tweaked.  If not, I'll open up a case with support.

 

Thanks,

 

Matt

Hi Matt,


There is no single setting that can address this limit, we will need to look into the Sfb configurations to find out what the possible cause is. A support case would be recommended. 

 

Thanks

David
