Elastic 6.2 and logstash

reinstalled everything (ES , logstash and kibana). Now i m back to my origional issue which was reported in Elastic node hangs (i think). So i have no idea what am i doing wrong ( There is nothing in grok failure logs , my logstash has debug on and has lines of my http server log entries. but in ES it just doesnt show up after some time.

any body experience this ?
