Bug ID: 53
Summary: rte abort issue on FreeBSD
Product: DPDK
Version: 18.05
Hardware: All
OS: FreeBSD
Status: CONFIRMED
Severity: major
Priority: Normal
Component: core
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
DPDK processes now allocates a large area of virtual memory address space,
with this change during rte_abort FreeBSD now dumps the contents of the
whole reserved memory range, not just the used portion, to a core dump file.
Write this large core file can take a significant amount of time, causing
processes to appear hung on the system.
The work around for the issue is to set the system resource limits for core
dumps before running any tests e.g."limit coredumpsize 0". This will
effectively disable core dumps on FreeBSD. If they are not to be completely
disabled, a suitable limit, e.g. 1G might be specified instead of 0. This
needs to be run per-shell session, or before every test run. This change
can also be made persistent by adding "kern.coredump=0" to /etc/sysctl.conf
