It will serve several requests correctly but then throw an exception upon the next request and then crash. I can reproduce the error using a bash loop that will wget the /jmx servlet every 2 seconds. My regionserver ultimately crashes within a few minutes. The regionserver log shows these exceptions (grep "Caused by"): {noformat} Caused by: java.lang.InternalError: Unsupported VMGlobal Type 177 Caused by: java.lang.InternalError: Unsupported VMGlobal Type 0 Caused by: java.lang.NullPointerException Caused by: java.lang.NullPointerException Caused by: java.lang.NullPointerException Caused by: java.lang.NullPointerException Caused by: java.lang.NullPointerException Caused by: java.lang.InternalError: Unsupported VMGlobal Type 0 Caused by: java.lang.InternalError: Unsupported VMGlobal Type 8192 Caused by: java.lang.InternalError: Unsupported VMGlobal Type 0 Caused by: java.lang.InternalError: Unsupported VMGlobal Type 0 Caused by: java.lang.InternalError: Unsupported VMGlobal Type 0 Caused by: java.lang.InternalError: Unsupported VMGlobal Type 0 Caused by: java.lang.InternalError: Unsupported VMGlobal Type 159785336 Caused by: java.lang.InternalError: Unsupported VMGlobal Type 159869880 Caused by: java.lang.InternalError: Unsupported VMGlobal Type 0 Caused by: java.lang.InternalError: Unsupported VMGlobal Type 0 Caused by: java.lang.NullPointerException {noformat} -- This message is automatically generated by JIRA.
