Hello all.
I found a strange error in log file which can cause worker restart. it
seems to be thrown by storm itself rather my program.
The error message is:
2017-04-26 19:14:34.721 o.a.s.m.n.StormServerHandler [ERROR] server
errors in handling the request
java.io.IOException: Connection reset by peer
