Getting error "This page isn’t working - HTTP ERROR 500" to check the scheduler logs or the failed backups

[donsan-git]

Hi,
I am getting the below error when trying to go to "Failed" backup nodes in the dashboard or trying to go to scheduler logs.
This page isn’t working - HTTP ERROR 500
I checked one of the previous cases and changed the "memory_limit" setting in /etc/php.ini from 128M to 1024M.
Also, checked the application log in /opt/cbackup/runtime/logs/app.log. The corresponding log message is given below. Could you please help?

I had also tried with system update. But, no luck!

SOMEONE PLEASE HELP
Below is the entry in the /opt/cbackup/runtime/logs/app.log when I tried to go to scheduler logs or to list the Failed nodes from dashboard

The problem is solved when I further increased the memory_limit in /etc/php.ini to 2048M. However, it is running slow,
I have another instance which is running fine with 128M itself and with good performance. There is something wrong or to be tuned!

I am still keeping this open as I want to see if there is any other issue (root cause)!

I am also seeing this issue on our server as well. Any help would be appreciated.
