dhcpcd crashes [solved]

fsckd · 2012-04-02 14:47:08

dhcpcd crashes sometimes. After resuming from hibernation (desktop machine, pm-hibernate) network doesn't work. So I restart it and, well, see for yourself.

> rc.d restart network

As you can see it works the second time, all within the same minute.

There's a bugrep submitted at https://bugs.archlinux.org/task/29200

And a solution is

export MALLOC_CHECK_=0

from German Arch forum

Thanks, I'll try that. It might be a while before I can say empirically if it worked.
As the discussions are occurring elsewhere I'll mark this as "solved".
