Hello,Not sure this is the right list, but as it seems related to a mlx4en device... # vmstat -i 1 (...) interrupt total rate cpu23:timer 1198 1127 # top -P ALL (...)

Initiating network connections to this server is now slow. And what I found is that I can't use netstat on my 2 mlx4en devices anymore (my monitoring tool is then no more fed). sysctl hw.mlxen0 is OK, no errors, and trafic counters grow slowly. What should I do ? How to investigate on this ? Thank you very much for your help & support,
Hi, Try "procstat -ak". It should give an idea what is going on. What version of FreeBSD is this? Is this a regression issue? --HPS _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
