Applies to: SynetoOS 4.4 and before


It may happen that SynetoOS Web Interface becomes hanged and doesn't respond anymore.


This behavior 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.


Step1. Login to SynetoOS.


Step2. Activate unsopported shell

unsupported shell

            or get SuperUser privileges

sudo su -


Step 3. Clear the PHP-FPM service maintenance status.

svcadm clear svc:/network/php-fpm:default


Step 4. 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 


Step 5. Restart Apache service.

svcadm restart svc:/network/http:apache


Step 6. Check PHP status.

svcs | grep php-fpm


Step 7. Check date and time since Apache restarted.

svcs | grep apache
