IRRd 4.1.8 was released on October 29th, 2021, and fixes two issues that occurred in all previous 4.1 releases:
- IRRd’s whois worker processes could use excessive memory #571
- The scopefilter_enabled value in the !J was incorrect in some cases #555
The memory issue occurred mainly when answering queries with large responses. Those cause high memory consumption in the workers, which is expected, but after answering the query, the workers did not always release the memory.
