Jon Siwek commented on BIT-1072:
--------------------------------

Regarding to core.leaks.basic-cluster test failure, the underlying cause of the leaks seems to be:

{noformat}
expression error in /home/jsiwek/bro/scripts/base/frameworks/sumstats/./plugins/./hll_unique.bro, line 56: field value missing [SumStats::rv1$hll_error_margin]
{noformat}

So seems that hook function needs better handling of uninitialized values and maybe also in this case values are expected to be initialized and are not.

> The branch adds support for the hyperloglog data structure.
> In the branch, core/leaks/basic-cluster.bro currently faisl. However, this seems to be unrelated to hll and just to be triggered by the addition of it to the sumstats tests. It looks like some kind of scriptland issue. pprof output is attached. (master, workers don't leak memory)
