Comment 3 Vladimir Stackov 2015-01-05 01:04:17 UTC

Same here.

Error is floating, can't get 100% reproducibility.

Comment 4 Thomas Moschny 2015-01-26 19:29:02 UTC

This is https://github.com/lxc/lxc/issues/403, and can be fixed with a mini-patch.

Not sure yet if this warrants a new build.

Comment 5 Thomas Moschny 2015-04-26 07:52:50 UTC

For the record, this will be in 1.0.8, once it's released.
