Subject: Re: Out of memory condition
Date: Fri, 5 Oct 2012 13:20:37 -0400 [thread overview]
Message-ID: <CALJXSJrbe62q6XCOf5xB6ra1kwSOnVyL6DvYqS7ncyUQndfkgw@mail.gmail.com> (raw)
In-Reply-To: <20121003205247.GO2370@localhost.localdomain>
I was able to reproduce the problem with the patch, now it fails in
extens_io.c instead of the compression module.
