which process consumes 100% CPU? Try `ps` or `top`. top - 12:01:32 up 1 min, 1 user, load average: 2.78, 1.04, 0.38 Tasks: 214 total, 3 running, 211 sleeping, 0 stopped, 0 zombie %Cpu(s): 17.6 us, 22.1 sy, 0.0 ni, 39.2 id, 0.0 wa, 0.0 hi, 21.0 si, 0.0 st KiB Mem : 7912980 total, 5899996 free, 1374436 used, 638548 buff/cache KiB Swap: 7815164 total, 7815164 free, 0 used. 6254020 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2138 root 20 0 6472 704 628 D 55.8 0.0 0:24.99 pptpgw 18 root 20 0 0 0 0 S 29.9 0.0 0:09.71 ksoftirqd/1 107 root 20 0 0 0 0 R 17.6 0.0 0:04.37 kworker/u4:5 2138 ?

That would be a mis-configuration. route1=192.168.4.0/24,[VPNIP],10 looks wrong. Does it work if you replace [VPNIP] with 0.0.0.0 ? If I boot the older kernel the same configuration works. I've tried with and without that route on there the result is the same. The problem is the one very important route is missing when I boot the latest kernel. This one: [VPNIPADDR] 192.168.0.1 255.255.255.255 UGH 0 0 0 wlp4s0 << MISSING FROM ABOVE Maybe the new fedora will fix this.. don't have time to upgrade at the moment and I can live with an older kernel. This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. Note the following stops the packet loop created by pptp sudo route add -host VPNIP/32 gw ORIGINALGATEWAYIP dev wlp4s0 |
