Applies to: SynetoOS 4.4 and before
It may happen that SynetoOS Web Interface becomes hanged and doesn't respond anymore.
This behaviour is related to a known PHP-FPM server issue (77430) present on all operating systems (Unix, Linux, Windows) and related to its memory stack management limitations. PHP-FPM developers are at work to solve it.
The steps below allow you to clear the memory stack and correctly restart SynetoOS Web Interface.
1. get SuperUser privileges:"admin" Activate unsupported shell and
un sh sudo su -
2. Clear the PHP-FPM service maintenance status.
svcadm clear svc:/network/php-fpm:default
3. Restart PHP-FPM service if the status is online, or enable it if the status is offline.
svcadm restart svc:/network/php-fpm:default svcadm enable svc:/network/php-fpm:default
4. Restart Apache service.
svcadm restart svc:/network/http:apache
5. Check PHP status.
svcs | grep php-fpm
6. Check date and time since Apache restarted.
svcs | grep apache
