[infinispan-issues] [JBoss JIRA] (ISPN-5930) OOM error when reqistering continuous query

Vojtech Juranek created ISPN-5930: ------------------------------------- Summary: OOM error when reqistering continuous query Key: ISPN-5930 URL: https://issues.jboss.org/browse/ISPN-5930 Project: Infinispan Issue Type: Bug Components: Server Reporter: Vojtech Juranek When running CQ perf tests in client-server mode, I hit following exception in HR server. The scenario was to store random texts in the cache and CQ which matches all the entries (i.e. query was "%"). Full logs from server are [here|https://jenkins.mw.lab.eng.bos.redhat.com/hudson/view/JDG/view/PERF-...]. Machines perf01-04 are servers, perf05-07 clients and perf08 is RG master. {noformat} 12:36:37,557 ERROR [org.infinispan.server.hotrod.HotRodEncoder] (HotRodServerWorker-9-33) ISPN005023: Exception
