Known issues
HQN-386003 - Correct MPS not to exceed the process' maximum number of mappings on Linux
it was found that the default max_map_count on Ubuntu and Red Hat was not sufficient to allow some jobs to complete normally even with a huge memory of 120Gb. The workaround is to set max_mem_count to 1048576, which prevents this stuck loop at the end of the job.
HQN-385981 - Cannot use /NumDisplayLists 2 with 'shared memory' backends
hen using /NumDisplayLists 2 in conjunction with an HVD TestConfig for GG_HHR_FRAMETIFF_SHM_ERR2 Rip can hang shortly after the HVD scan. We’re advised against doing this see release notes for v14.0r0.
HQN-385923 - Scalable crashes on startup on PCs with CPUs without AVX2 support
Running a scalable RIP on an Ubuntu VM without AVX2 SIMD support can result in a crash from ZeroMQ initializing static data. Checking the CPU flags for the VM revealed it did not have AVX2 enabled.
