**Kibana version** : 8.14 **Elasticsearch version** : 8.14 **APM Server version** : 8.14 **APM Agent language and version** : 1.50 Hi, We try to debug slow response in java app using elastic APM. We got something like a black holes, about 7 secs when nothing is reported and we don't know why this high latency came in. ![obraz](https://us1.discourse-cdn.com/elastic/original/3X/e/8/e809048fd66876448a31b62b2007281b87858812.jpeg) Any ideas what happened between SELECT FROM dbo.PROCESS\_INSTANCES and UPDATE SPRING\_SESSION ? ---

Your transaction likely spends its time in code that is not covered by our [supported instrumentations](https://www.elastic.co/guide/en/apm/agent/java/current/supported-technologies-details.html). You can use the [inferred spans feature](https://www.elastic.co/guide/en/apm/agent/java/current/config-profiling.html#config-profiling-inferred-spans-enabled) to use profiling to uncover which code causes this latency.
