As stated in the other thread ( you might consider only using ONE thread for the same issue, to avoid double, trible... posts ), phpmyadmin runs via the sw-cp-server ( a very own Plesk-nginx-webserver ), which is a part of Plesk. The installed webserver components apache2 and/or nginx have nothing to do with it.

Please investigate any issues with phpmyadmin over the sw-cp-server - logfiles and/or configurations files.

2015/01/03 11:18:17 [error] 29740#0: *539 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: xxxx, server: , request: "POST /domains/databases/phpMyAdmin/import.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/sw-engine.sock:", host: xxxx:8443", referrer: "https://xxxx:8443/domains/databases/phpMyAdmin/index.php"

Hi Ahmad12,

such issue mostly indicate, that the FastCGI - process for the sw-cp-server isn't working properly or could be stuck for some reason, or isn't running at all for some reasons. Please consider restarting the sw-engine-fpm and maybe as well the sw-cp-server to solve your issue.

Please use ...

/etc/init.d/sw-engine restart && /etc/init.d/sw-cp-server restart
​

to restart sw-engine-fpm and sw-cp-server, or check the status with the commands "/etc/init.d/sw-engine status && /etc/init.d/sw-cp-server status"


If you experience such an issue quite regulary, please consider tweaking your depending configuration files for the Control Panel ( please see the link above to inform yourself about the paths ) or switch to a debug - log mode, to investigate the cause.
