Curious, to anyone reading this — anyone think that this could be the same bug: https://bugs.schedmd.com/show_bug.cgi?id=2493 -- ____ || \\UTGERS, |---------------------------*O*--------------------------- ||_// the State | Ryan Novosielski - [email protected] || \\ University | Sr. Technologist - 973/972.0922 (2x0922) ~*~ RBHS Campus || \\ of NJ | Office of Advanced Research Computing - MSB C630, Newark `'
