In https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195970, Larry Rosenman suggested setting net.graph.maxdata=8192. I set it to 4096, and the problem seems to have gone away (I am currently testing, and it has not failed so far).
This is actually mentioned in https://wiki.freebsd.org/VirtualBox/Tuning, but I would never have guessed that the standard network stack is affected by setting this tunable: I am not copying anything in/out of the VB client, but rather run a completely independent regular IPv4 transfer alongside it. Maybe the description there could be expanded accordingly. Anyway, thanks to Larry for pointing me in the right direction. -- Martin _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-emulation To unsubscribe, send any mail to "[email protected]"
