Issues After Switch to PHP-FPM

I switched over to PHP-FPM using PHP 7.0x and and Memcached (all sites use https) and I have a few issues:

1) I can't be sure that all of my cron jobs are running correctly. They are in this format in the root cron job /var/spool/cron/root :

SHELL="/bin/bash"
*/5 * * * * /usr/local/cpanel/scripts/dcpumon-wrapper >/dev/null 2>&1

The ones that seem to not work optimize my databases, and include a hook to email me when done, and I seem to have stopped getting the emails:

SHELL="/bin/bash"
22 0 * * 3,5 (mysqlcheck -op -u root database_name_here -pMYPASS 2>&1 | mail -s "optimizeDB Articles Output" myemail@gmail.com)

It's possible that they are all working, and that I'm not getting email. But is there a format change to cronjobs when switching to PHP-FPM?


2) Most of the time I can't SFTP to the server until I restart the PHP-FPM Apache service. I suspect that this has to do with my resource settings. My server is very busy. What setting should I look to increase in order to be able to connect again with SFTP?


3) I made the switch to PHP-FPM from SUPHP for performance reasons, however, is there a configuration for security settings for PHP-FPM that I need to edit? Are there settings like in SUPHP somewhere?

 

1) Regarding my cron jobs, this format cron is no longer working at all, but it turns out crons in the other format listed above are running. Is there another way to write this type of cronjob so that it will run? I will assume that either the recent major apache update I ran broke this, or my switch to PHP-FPM did:

SHELL="/bin/bash"
22 0 * * 3,5 (mysqlcheck -op -u root database_name_here -pMYPASS 2>&1 | mail -s "optimizeDB Articles Output" myemail@gmail.com)

2) My FTP client throws an "unknown socket error" and here is what the log records. Again, I must restart the apache PHP-FPM to be able to connect using SFTP. I suspect it is a resource issue, perhaps with my PHP-FPM config settings, but I've tried dozens of different config settings and none seem to fix this issue (no, the link to the cpanel documentation does little to help one figure out the correct config settings, sorry, but that is nearly always the case with links to cpanel documentation--you guys throw these links around, but they rarely contain real world examples of config files for different server configurations, which would be the kind of info that would actually be helpful--but I do appreciate your attempt to help me!):

/var/log/secure:

I will create a ticket and let you know what I find, as the SFTP connection issue is still a problem. I have a busy site, a suspect it is a resource issue.

Also, this type of cron is working...I am not 100% sure why it wasn't directly after I switched to PHP-FPM, but once I increased various resource settings it seems to work fine now.
