Comment 2 for bug 1601893

Thanks for reporting bug.
what plugin (lma_collector) version do you have ? My guess is 0.8.0. if it is the case I invite you to upgrade to 0.8.1 which solves your issues. If it's a production environment and you cannot redeploy, we have a procedure which describes the upgrade.

you're hitting a caracteristic bug where heka is stucked and collectd starts to drop metrics: this is fixed with 0.8.1
