The IRC discussion I found in my log indicates that it was removed because it didn't apply cleanly due to changes when updating to 4.9.75, yet I don't think anyone independently validated that the changes made are equivalent to the patch that was removed. I was never able to reproduce this issue, so I didn't investigate it myself. -- Kevin Stange Chief Technology Officer Steadfast | Managed Infrastructure, Datacenter and Cloud Services 800 S Wells, Suite 190 | Chicago, IL 60607 312.602.2689 X203 | Fax: 312.602.2688 kevin at steadfast.net | www.steadfast.net
