we are using the Dynatrace 7.1, I know Dynatrace 7.1 support has been approaching to the EOL but wondering if this issue still exist or not in newer release. We are migrating to Dynatrace 7.2 but there is license issue and for which separate communication happening with Dynatrace team. Meanwhile, we required to resolve this issue.
For now, i have excluded "ogr.apach.tomcat.dbcp" package for smooth process. But, required concrete solution.
Issue is; i am getting below error in thread dump
"IM Trigger Scheduler" tid=0x47 in RUNNABLE
