Resolved What is the Pdo.php error meaning?

raytracy

Basic Pleskian
I found my /var/log/message show the following messages every 5 minutes:

Jul 17 19:31:30 psa-fbb wdcollect: PHP Warning: Error while sending QUERY packet. PID=1825 in /usr/local/psa/admin/externals/Zend/Db/Statement/Pdo.php on line 228

But it did not show neither in before nor in my other hosts, I found it only persist in a single host.

What does it mean? And how can I fix it?

By the way, before this message shown, this host have experienced a memory exhausted incident and forced to reboot. The message began shown constantly after rebooted.
 
Please try to increase wait_timeout in my.cnf:

wait_timeout = 28800

and restart mysql service after that. I hope it will help.

Still same....not worked.

I have try to inspect db by: plesk repair db -d, but there is no error found.

Is there any log help?
 
I would suggest you try to reinstall Watchdog system monitoring component.
 
I can only recommend creating a request to support team to do the in-depth investigation to find the reason and to fix it. Please create a ticket to support at Help Center
