Btw., the large number of AF_INET sockets is a result of the way how Cygwin implements AF_LOCAL sockets: They are emulated by local AF_INET sockets since WIndows doesn't know the concept of AF_LOCAL sockets. Note that there are still sleep processes running. So on a hunch I just added a `sleep 30' between the two tests and, lo and behold, the forwarding.sh test completes successf...

Hi All, I have recently moved by webmail server from a VPS to a hosted dedicated server running Ubuntu 16.04. Everything is fine except that login is particularly and consistently long (around 4-5 seconds). I have noticed that the process dovecot/auth seems to eat all of the resources of one of the cores available on the host during login. The authentication backend is a postgres database which

Hello everybody! We have a cluster of servers managed by VMmanager 5 KVM (by ispsystem). A typical node: # cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core) # uname -r 3.10.0-693.11.6.el7.x86_64 # rpm -qa |grep libvirt libvirt-daemon-driver-qemu-3.7.0-1.el7.centos.x86_64 libvirt-daemon-driver-storage-disk-3.7.0-1.el7.centos.x86_64 libvirt-3.7.0-1.el7.centos.x86_64

as the next klibc release 1.5.16 looks like shaping up, I have a trouble to build that for Debian. currently I build depent on linux-libc-dev, I don't know what against I can build latest klibc, see klibc fails to build due too: make -C linux/ ARCH=x86_64 INSTALL_HDR_PATH=debian/tmp/usr/lib/klibc/ headers_install make[3]: *** No rule to make target `headers_install'. Stop. make[2]: ***
