We have a gitlab instance where backup runs every day the size of data is 72 GB and the tar file size is 36 gb after backup. during this time the application is going down.
nginx log :
2016/01/07 14:24:19 [error] 24178#0: *1898 connect() to unix:/home/git/gitlab/tmp/sockets/gitlab.socket failed (11: Resource temporarily unavailable) while connecting to upstream,
cpu usage is flucuating between 60- 400%
Can some suggest some measures to solve this downtime.
