--- Begin Message ---Package: pptpd Version: 1.3.4-5 Severity: grave Justification: renders package unusable PPTP was running flawlessly before doing an upgrade. Details: Recently converted a x86 32 bit system to 64bit amd64. The installed system was comletely migrated to amd64 inclucing all packages. Installed new Supermicro X9SRL-F motherboard and Intel Xeon E5-2609. Upgraded memory from 6GB to 32GB. Intial PPTP connections are fine. If a high volume of traffic is sent over the VPN, the connection drops and the error log outputs: pptpd[7894]: GRE: xmit failed from decaps_hdlc: No buffer space available pptpd[7894]: CTRL: PTY read or GRE write failed (pty,gre)=(6,7) Running: strace pptpd --fg -d results with this output during the connection drop: ) = ?

Now, write(2) or writev(2) system call is not documented as possibly returning ENOBUFS, but it probably should be. Whether your kernel is correct in this or not is not something I've researched. The code in pptpd fails if ENOBUFS occurs in this way. I've tried versions 1.3.4-3, 1.3.4-5.1, and 1.3.4-5. ppp is 2.4.5-5.1+b1 kernel is 3.2.0-3-amd64 bcrelay is 1.3.4-5 -- System Information: Debian Release: wheezy/sid APT prefers testing-updates APT policy: (500, 'testing-updates'), (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-3-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=ANSI_X3.4-1968) (ignored: LC_ALL set to C) Shell: /bin/sh linked to /bin/bash Versions of packages pptpd depends on: ii bcrelay 1.3.4-5 ii debconf [debconf-2.0] 1.5.46 ii libc6 2.13-35 ii libwrap0 7.6.q-24 ii netbase 5.0 ii ppp 2.4.5-5.1+b1 pptpd recommends no packages. pptpd suggests no packages. -- Configuration Files: /etc/pptpd.conf changed: speed 115200 option /etc/ppp/pptpd-options debug logwtmp localip 192.168.9.1 remoteip 192.168.9.224-231 pidfile /var/run/pptpd.pid bcrelay eth1 -- no debconf information
