> Hi,
> I'm using a kafka_2.10-0.10.1.1 with 3 brokers cluster.
> A few days ago, we started running out of FS and our System Admin allocated
> some more Disc space. After the allocation, we started experiencing high lags
> on the consumers which kept growing.
> On the Consumer side, we saw that no data is being consumed and the following
> message keep coming in the log files:
> o.a.k.c.c.internals.AbstractCoordinator : (Re-)joining group
> AutoPaymentSyncGroup
>
> On the Broker logs, we keep seeing seeing messages of restabilize group :
> [2018-09-27 18:38:16,264] INFO [GroupCoordinator 0]: Preparing to restabilize
> group AutoPaymentActivityGroup with old generation 357
> (kafka.coordinator.GroupCoordinator)
> [2018-09-27 18:38:16,264] INFO [GroupCoordinator 0]: Preparing to restabilize
> group AutoPaymentCreditCardTypeGroup with old generation 278
> (kafka.coordinator.GroupCoordinator)
> [2018-09-27 18:38:16,284] INFO [GroupCoordinator 0]: Preparing to restabilize
> group AutoPaymentAuthChannelGroup with old generation 349
> (kafka.coordinator.GroupCoordinator)
> [2018-09-27 18:38:16,411] INFO [GroupCoordinator 0]: Preparing to restabilize
> group AutoPaymentAuthCodeGroup with old generation 284
> (kafka.coordinator.GroupCoordinator)
> [2018-09-27 18:38:16,463] INFO [GroupCoordinator 0]: Preparing to restabilize
> group AutoPaymentInteractionSyncGroup with old generation 359
> (kafka.coordinator.GroupCoordinator)
> [2018-09-27 18:38:16,464] INFO [GroupCoordinator 0]: Preparing to restabilize
> group AutoPaymentSyncGroup with old generation 358
> (kafka.coordinator.GroupCoordinator)
>
> After bouncing the broker, the issue was resolved.
> Thanks,
> Boaz.
