Created attachment 372766 [details] kernel trace from ipset -L
Also, the CPU spikes at 100% Can't kill the ipset process. # ps ax -o comm,wchan | grep ipset ipset nfnl_lock
There is a 6.21.1 version out there that might fix this.
I tried: wget .. ipset-6.21.1.tar.bz2 tar -xjf ipset-6.21.1.tar.bz2 cd ipset-6.21.1 ./configure --prefix=/usr/local cd src ./ipset -L Same results. ipset worked just fine 'till I enabled some iptables/nf_tables/ipset stuff in the kernel ( can't remember which ).
(In reply to Sandu Adrian from comment #4) > ipset worked just fine 'till I enabled some iptables/nf_tables/ipset stuff > in the kernel ( can't remember which ). Well then figure that part out. I can't reproduce locally on 3.15.0
what about 6.24?
retest on 6.29
At this time, I don't have access to the machine anymore ( don't even know what happened to it .. ). I guess we can safely close this, was a weird machine anyway.
