[Bug 1423631] Re: tap interface drops many packets on highload systems
I found the cause of the problem. The tap interface of a instance has small tx length 500 packets. At a high network load (15-25 Kpps) and high CPU load on a guest some times queue overflows and the tap interface start drop network packages. I think that queue overflow occurs in moments of micro friezes (<1000ms) of a virtual machine. I solved this problem by increasing the tx_queue up to 1. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1423631 Title: tap interface drops many packets on highload systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1423631/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
