Splunk AddOn Microsoft Cloudservices Memory Leak?

Loves-to-Learn Lots

We're seeing severe memory issues with the Splunk AddOn for Microsoft Cloudservices where a single python process can consume well over 200Gb of memory, ultimately being reaped by the OOM Killer.

These are Azure Firewall collections. Rather critical to our logging infrastructure and we have no information as to why this is happening. It doesn't happen to all collections, but does happen to many ... You can see below, one child process consuming > 60Gb ... and Splunkd having grown to 275Gb of virtual memory.

Did you ever get any traction on this? I have the same exact issue on two servers. One has 16GB of memory, the other has 56GB. Both seem to hover around the 68% mark for RAM usage.
