Hi all, seems like there is a bug with "git rerere gc" not understanding grace periods like "60 days" defined in the config. What I did: git config gc.rerereresolved "60 days" git gc results in: Counting objects: 158790, done. Delta compression using up to 8 threads. Compressing objects: 100% (26849/26849), done. Writing objects: 100% (158790/158790), done. Total 158790 (delta 116114), reused 158790 (delta 116114) fatal: bad numeric config value '60 days' for 'gc.rerereresolved': invalid unit error: failed to run rerere git --version = git version 2.13.0 Best regards, Uwe
