Hello, I?m running into an occasional problem where rte_eal_init() returns -ENOMEM and the following error is logged:
EAL: Can only reserve 991 pages from 1024 requested Current CONFIG_RTE_MAX_MEMSEG=256 is not enough When this happens a reboot will take care of it, but I?m hoping for a more elegant solution. I don?t have much direct experience with hugetlbfs so I?m hoping someone on this list can suggest something. I did boost max-memseg and it works, but I?m worried that it will just crop up again - I instrumented rte_eal_hugepage_init() and found that the number of segments used slowly creeps up as I cycle my application (i.e. repeated rte_eal_init() invocations with process-type == primary). I?m theorizing that hugetlbfs fragments (for lack of a better phrase) over time. Does anyone on the list know of a way to reset hugetlbfs short of rebooting?
