• Issues:

customer report that real time will interrupted frequently as below:

  • Root Cause:

some storm workers execute full gc with too many time and cause nimbus reset the worker , so the data is missing.

  • Steps to invesigates this issues

1. check the storm UI with workers and found that all workers are normal ,but some task failed

check logs from storm workers and found there are some exceptions as below:

it seems that some of workers can't connect and also can find others exceptions of "Connection reset by peer" with zookeeper cluster and kafaka cluster , check the port usage and found that :

tcp6       0      0 10.9.248.61:38050       10.9.248.70:9092        TIME_WAIT

we restarted all storm workers and kafaka cluster and zookeeper cluster , the issue not fix also.

we check the storm workers again and found on other workers there also have some issues as below:
