been using gitlab for the past two years at work and the only time it's inaccessible is when upgrading it. it does have a lot of other issues like response time and a difficult to navigate ui but crashing is not one of them.
What version are you on? Since GitLab 8.0 great improvements have been made to the UI and if there is something still wrong on the latest version we would love to know.
it is generally hard to navigate, every time i'm adding a user and giving him access to groups/projects i have to spend a minute to figure out where. the new CI gui is worse than the old one (pre-8).
