the Java Runtime Environment | Problematic frame:sigar-amd64-winnt.dll+0x14ed4

"sigar-amd64-winnt.dll" is triggering the error. The details will be in the 
core dump.

The vendor which supports "sigar-amd64-winnt.dll" will need to fix it.
Based on the release revisions, I suspect the DLL is using a reference to a 
request or response object *after* the request was already completed.
This is not allowed since 9.0.90. In particular - see the notes about 
"RECYCLE_FACADES" here https://tomcat.apache.org/tomcat-9.0-doc/changelog.html


An alternative is removing "sigar-amd64-winnt.dll" from lib (but I suspect the 
application will be broken)
