https://bugzilla.redhat.com/show_bug.cgi?id=760177 --- Comment #27 from Marek Vavrusa <marek.vavrusa@xxxxxx> --- So there are two possible issues here. 1 - glibc 2.12 exported the recvmmsg symbol event if it wasn't supported by the kernel version and Knot didn't detect it well. This is fixed in latest release (1.1.0) 2 - glibc 2.12+ & kernel-2.6.32-* present in f.e. EL6/CentOS6 has broken implementation of recvmmsg() that doesn't support MSG_WAITFORONE as it should. The expected behavior is to set MSG_DONTWAIT after first received packet, but it doesn't do so, so the answering is stuck until you supply at least ~ 20 queries. This behavior is probably something that will be hard to detect on runtime and therefore, I recommend turning off recvmmsg() support for broken platforms with: ./configure --enable-recvmmsg=no -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ package-review mailing list package-review@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/package-review
