gitlab登录页面500错误

linux7虚拟机安装的gitlab12.4.2,一值用的好好的,突然登录页面就打不开了报500错误。查看了内存、数据库关系、子服务状态,都正常运行。
运行命令gitlab-ctl tail gitaly,查看gitlab日志,“error”:"rpc error: code = Internal desc = exit status 128"错误。
请问这个问题该怎么解决?

可以看看/var/log/gitlab/gitlab-rails的日志呢

Completed 500 Internal Server Error in 2129ms (ActiveRecord: 172.9ms | Elasticsearch: 0.0ms)

ActionView::Template::Error (13:exit status 128):
25: - if project.creator && use_creator_avatar
26: = image_tag avatar_icon_for_user(project.creator, 48), class: “avatar s48”, alt:’’
27: - else
28: = project_icon(project, alt: ‘’, class: ‘avatar project-avatar s48’, width: 48, height: 48)
30: .flex-wrapper
31: .d-flex.align-items-center.flex-wrap.project-title

请问这个错误该怎么解决啊?

这个报错不明显,看下rails下的production的日志和exception的日志
