Description
Netdata is an open source observability tool. Prior to 2.10.4, an authenticated child agent can send an oversized CHART SLOT value that str2ull_encoded passes to pluginsd_rrdset_cache_put_to_slot in src/plugins.d/pluginsd_internals.h. The accepted slot drives reallocz to request an approximately 16 GiB chart-pointer array, and allocation failure invokes fatal and aborts the parent Netdata agent, repeatedly disabling centralized monitoring while stream access persists. This issue is fixed in version 2.10.4 and nightly build 2.10.0-782-nightly.
