Increasing the default vm.max_map_count value
- frankjr 3y ago> Using a high VMA count usually implies that the application is doing something suboptimal. Having many VMAs can degrade performance of MM operations and result in memory waste. > Running into VMA limits usually implies that the application is not optimized and should handle things differently. Likely, the memory allocator is doing something "bad" (e.g., mmap()+munmap() instead of MADV_DONTNEED) and should be optimized. https://lore.kernel.org/lkml/1a91e772-4150-4d28-9c67-cb6d0478af79@redhat.com/ https://lore.kernel.org/lkml/1a91e772-4150-4d28-9c67-cb6d047...
