Resolved Login hangs plesk 12.5.30

[aresblade]

Hi
i have the plesk panel that hangs at login, after user and password, it simply hangs with a blank page, with no errors, where can i go via ssh to check the issue? thanks

I have found this in
/var/log/sw-cp-server/error_log

2016/08/30 16:33:31 [error] 10081#0: *172 upstream timed out (110: Connection timed out) while reading response header from upstream, client:0.0.0.0, server: , request: "GET /smb/ HTTP/1.1", upstream: "fastcgi://unix:/var/run/sw-engine.sock", host: “0.0.0.0.:8443", referrer: "https://0.0.0.0:8443/login_up.php3?success_redirect_url=https://0.0.0.0:8443/"

p.s. i changed the real ip to 0.0.0.0

As possible workaround, remove lock_manager temporary files:

# rm -f /usr/local/psa/var/cache/SharedLockManagerStorage*

Then restart services:

# service sw-engine restart && service sw-cp-server restart

Also it would be useful to run

# plesk repair installation

Thank you it worked!
maybe the problem was caused by Plesk component upgrade' , i found in the log many lines of component upgrade before i had the issue.
cheers
