Sometimes adding comments "Build Started" by gerrit-trigger-plugin from specific Jenkins server more than 2 jobs running to Gerrit server, fails.
In case Jenkins has 2 jobs and these are triggered by uploaded patchset on gerrit,
either "Build Started ... (1/2)" or "Build Started ... (2/2)" cannot be upload sometimes .
Here is the stacktrace, issue happens in gerrit-events package :
java.io.IOException: Error during sending command

In my investigation, It seems that simultaneous attempt of review gerrit's ssh commnd causes error:
"cannot post review
one or more reviews failed; review output above", these messages are defined/returned from Gerrit. https://code.google.com/p/gerrit/issues/detail?id=3730
Issue may be in Gerrit side, but in the meantime, adding review comments of Gerrit ssh command to Gerrit server should be retry-able for Jenkins side.
environment:
gerrit-events :2.7.1
gerrit-trigger:2.14.0
