[jira] [Created] (CASSANDRA-14686) Jolokia agent not accepting
requests during an operation
Cyril Scetbon created CASSANDRA-14686:
-----------------------------------------
Summary: Jolokia agent not accepting requests during an operation
Key: CASSANDRA-14686
URL: https://issues.apache.org/jira/browse/CASSANDRA-14686
Project: Cassandra
Issue Type: Bug
Components: Core
Environment: Cassandra 3.11.2
Ubuntu Xenial
Jolokia 1.3.7
Reporter: Cyril Scetbon
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 :
{code:java}
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
{code}
I also removed the default flag [-XX:+PerfDisableSharedMem|https://github.com/apache/cassandra/blob/cassandra-3.11/NEWS.txt#L769-L771] but did not get more luck.
