If you have a cap file with a lot of APs, this means aircrack ends up using a lot of memory it doesn't need or ever use. I noticed when I tried to run it in an wrt54g router and it failed even before starting to crack because there wasn't enough memory. I ran aircrack-ng on a PC over the same cap file and I saw it was taking over 40mb of memory just for starting to crack. Also note that even if you don't intend to use the ptw attack (with opt. -z) the structures are allocated.\n\n\nMigrated-From: https://trac.aircrack-ng.org/ticket/188"},"comment":{"url":"https://api.github.com/repos/jbenden/aircrack-ng/issues/comments/362844884","html_url":"https://github.com/jbenden/aircrack-ng/issues/188#issuecomment-362844884","issue_url":"https://api.github.com/repos/jbenden/aircrack-ng/issues/188","id":362844884,"user":{"login":"jbenden","id":73767,"avatar_url":"https://avatars3.githubusercontent.com/u/73767?v=4","gravatar_id":"","url":"https://api.github.com/users/jbenden","html_url":"https://github.com/jbenden","followers_url":"https://api.github.com/users/jbenden/followers","following_url":"https://api.github.com/users/jbenden/following{/other_user}","gists_url":"https://api.github.com/users/jbenden/gists{/gist_id}","starred_url":"https://api.github.com/users/jbenden/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jbenden/subscriptions","organizations_url":"https://api.github.com/users/jbenden/orgs","repos_url":"https://api.github.com/users/jbenden/repos","events_url":"https://api.github.com/users/jbenden/events{/privacy}","received_events_url":"https://api.github.com/users/jbenden/received_events","type":"User","site_admin":false},"created_at":"2018-02-03T18:57:13Z","updated_at":"2018-02-03T18:57:13Z","author_association":"OWNER","body":"**Modified by misterx on 28 Apr 2007 13:53 UTC**"}}
