Hi Gordon, Just to make sure, did you check out the v15-dev branch of user-cr? By default you get the v14 branch which is not compatible. I suspect you're using v14 becaues sys_checkpoint is being called with flags 0, not 4, which is (now) wrong. thanks, -serge > dmesg: > [ 3948.213442] ckpt[3218]: segfault at 46 ip b7e1213d sp bf835e18 > error 4 in libc-2.7.so[b7db4000+155000] > > Any idea what may be the problem? > Do i have a problem with my libc? > > My System spec: > Debian 5.0 i686 > CPU: AMD Athlon XP 2000+ > > Regards, > Gordon > _______________________________________________ > Containers mailing list > Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx > https://lists.linux-foundation.org/mailman/listinfo/containers _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
