[ASF BZ 62892] tomcat-native memory leak when using Mutual authentication + OCSP

Customer noticed the native memory increase when using Mutual authentication and OCSP on tomcat8, they are using this script:

$ cat /root/certs/tomcat_watcher.sh 
#!/bin/bash
pid=$1
counter=1
until [ $counter -gt 240 ]
do
currentdate=$(date +"%m-%d-%Y %H:%M:%S")
privatemem=$(echo 0 $(awk '/Private/ {print "+", $2}' /proc/$pid/smaps) | bc)
echo $currentdate,$privatemem
 ((counter++))
sleep 30
done

and running it as ./tomcat_watcher.sh <tomcat8_pid>. The result is that the memory increases during the load test, if they test with no Mutual authentication and OCSP, there is no such issue. I have tested in my environment with the following versions:

• jws3.1 rpm install,
• tomcat-native-1.2.8-10.redhat_10.ep7.el7
• rhel 7.4

I have used tomcat-native-1.2.8 as it is listed in the supported configuration for JWS 3.1, I can replicate the issue when the server is not used.
