Hi All, I'm using logstash to ingest data into elasticsearch, while executing logstash its throwing up java heap space error. There is almost 5450 documents i'm trying to ingest. Any ideas or suggestions where i should look into for this error? ``` /usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/rufus-scheduler-3.0.9/lib/rufus/scheduler/cronline.rb:77: warning: constant ::Fixnum is deprecated % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 2048k 100 2048k 0 0 737k 0 0:00:02 0:00:02 --:--:-- 737k java.lang.OutOfMemoryError: Java heap space Dumping heap to java_pid2962.hprof ...

What does your filter configuration look like? Are you splitting an array? ---

@Badger i have 3 different filters configured, ``` filter { json { source => "message" } split { field => "results" } prune { blacklist_names => ["command", "host", "message"] } } ``` This is my document, ``` "results": [ { "IPAddress": "1.9.7.2", "Caption": "APPV1", "NodeID": 1, "DNS": "appv1.global.com", "Vendor": "Windows", "Location": "", "MachineType": "Windows 2016 Server", "StatusDescription": "Node status is Up, One or more application monitors is Down, Intel(R) 82574L Gigabit Network Connection #2 ยท eth2 is in an Unknown state, One or more AppInsight for IIS monitors is in an Unknown state.", "Status": 1, "Severity": 5001, "TotalMemory": 6.871887E+10, "PercentMemoryUsed": 30, "CPUCount": 25, "CPULoad": 28, "LastBoot": "2020-05-26T14:25:00.0000000", "StatusLED": "Up.gif " }, ``` If i try to ingest 2000 documents its working, when the count goes above 2000 then its throwing error.
