Hey, Srinivasa. It sounds like you’re running an intermediate version of the master branch (I remember that specific error as I was making some changes). It should be resolved with the latest version of master. Can you try pulling the latest master?
We’ll be cutting a new release version soon, as there have been a number of changes and updates that are useful. In the meantime, you may find more help if you post to our Gitter: https://gitter.im/linkedin-Burrow/Lobby -Todd On Thu, Mar 1, 2018 at 11:58 PM, Srinivasa Balaji < srinivasa_bal...@trimble.com> wrote: > We are running burrow version3 for kafka consumer lag monitoring, > > Issue is burrow service is getting down frequently which is every 1hr, > > Command used to start the burrow service > > # nohup $GOPATH/bin/Burrow --config-dir /opt/work/src/github.com/ > linkedin/Burrow/config 1>&2 & > > We are seeing the below mentioned error in log > > <SNIP> > > panic: interface conversion: interface {} is nil, not *storage.brokerOffset > > goroutine 85 [running]: > github.com/linkedin/Burrow/core/internal/storage.(* > InMemoryStorage).fetchTopic(0xc4201d65a0, 0xc42100b8f0, 0xc42034d800) > /opt/work/src/github.com/linkedin/Burrow/core/internal/ > storage/inmemory.go:611 +0x3c8 > github.com/linkedin/Burrow/core/internal/storage.(* > InMemoryStorage).(github.com/linkedin/Burrow/core/internal/ > storage.fetchTopic)-fm(0xc42100b8f0, 0xc42034d800) > /opt/work/src/github.com/linkedin/Burrow/core/internal/ > storage/inmemory.go:182 +0x3e > github.com/linkedin/Burrow/core/internal/storage.(*InMemoryStorage). > requestWorker(0xc4201d65a0, 0x11, 0xc4201d4900) > /opt/work/src/github.com/linkedin/Burrow/core/internal/ > storage/inmemory.go:190 +0x105b > created by github.com/linkedin/Burrow/core/internal/storage.(* > InMemoryStorage).Start > /opt/work/src/github.com/linkedin/Burrow/core/internal/ > storage/inmemory.go:144 +0x28b > > > </SNIP> > > > Kindly let us know your thoughts on this to fix it. > > ———————————————- > <http://www.trimble.com/> > Srinivasa Balaji L > Principal Architect Cloud & DevOPS - TPaaS > 10368, Westmoor Drive, Westminster, CO 80021 > *M*: +1(303) 324-9822 <+919790804422> > *Email*: lsbal...@trimble.com > -- *Todd Palino* Senior Staff Engineer, Site Reliability Data Infrastructure Streaming linkedin.com/in/toddpalino
