This scenario is relatively easy to Reproduce by running the following script ``` drill_home=/data/shf/apache-drill-1.22.0-SNAPSHOT/bin fileName=/data/shf/1s/shf.txt random_sql(){ #for i in `seq 1 3` while true do num=$((RANDOM%22+1)) if [ -f $fileName ]; then echo "$fileName" " is exit" exit 0 else $drill_home/sqlline -u \"jdbc:drill:zk=jupiter-2:2181/drill_shf/jupiterbits_shf1\" -f tpch_sql8.sql >> sql8.log 2>&1 fi done } main(){ unset HADOOP_CLASSPATH #TPCH power test for i in `seq 1 25` do random_sql & done } ``` > Sender memory leak when rpc encode exception > -------------------------------------------- > > Key: DRILL-8489 > URL: https://issues.apache.org/jira/browse/DRILL-8489 > Project: Apache Drill > Issue Type: Bug > Components: Server > Affects Versions: 1.21.1 > Reporter: shihuafeng > Priority: Major > Fix For: 1.22.0 > > -- This message was sent by Atlassian Jira (v8.20.10#820010)
