>Synopsis: Kernel lock vmmaplk using net/toxic >Category: Kernel >Environment: System : OpenBSD 7.2 Details : OpenBSD 7.2-current (GENERIC.MP) #874: Fri Dec 9 10:09:48 MST 2022 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64 Machine : amd64 >Description: Process net/toxic will lock the kernel after a period of time. The duration is random. I have seen this be as fast as a few minutes to a few hours. The program top(1) will eventually reveal toxic is in "vmmaplk". At this point the system can not be rebooted and new users can no longer log in. Toxic uses a lot of vfork, mlock, munlock, and mmap with threads. This could be a result of the toxcore libary. This has been reproduced on completely different amd64 hardware. >How-To-Repeat: 1) Run toxic and wait for it to enter "vmmaplk" in top(1). 2) Try to reboot(8) the system. >Fix: No known fix.
