Description

I've noticed that when I run a long operation like a rebuild using Jolokia, I can no longer query Jolokia and get a timeout error even when trying to read a simple attribute like the Java version in use : 

jmx4perl http://cassandra-3.11.2:8778/jolokia read java.lang:type=Runtime SpecVersion
ERROR: Error while fetching http:// cassandra-3.11.2:8778/jolokia/read/java.lang%3Atype%3DRuntime/SpecVersion :
408 Got timeout in 180s

I also removed the default flag -XX:+PerfDisableSharedMem but did not get more luck.
