Mysqld Hight CPU Usage when I use the Multimedia Application

Post by papas70 »

Hi,
When I use the Multimedia Applications like QuMagie che Mysqld process take over 50% of CPU and the whole performance system goes down. Often during use the QuMagie I receive the timeout (the screenshot attached is timeout during the list of similar photos). This problem it's the same when I use the mobile app. During these actions there is only one user connected and no more requests requests are queued by other users or process.

My Qnap TS-251D is often in a stressed state when I use the mutimedia application because the Mysqld process use always at least 50% of CPU.

Do you have any ideas to help me?

Hi,
the Qnap is not exposed to the web and I access to it only by VPN. The Mysqld goes down to the CPU usage after 15/20 minutes that I don't use the Multimedia Applications.
Nobody use the Qnap only one user logs in.

I would open a ticket with qnap, glitches in the software are something we can do nothing about (user forum)

Hi papas70,
did you get any response from the other support team? I have the same problem on my TS-431P:
PID USER STATUS RSS PPID %CPU %MEM COMMAND
7796 admin S 23M 1 37.5 2.3 mysqld
20413 admin S 4856 1 7.0 0.4 mysqld
29189 admin S 2472 1 5.6 0.2 myidbserver

Maybe their hints can help me also.

Hi,
good news...The support by remote support did something because my problem has been resolved. I asked to the support what the second level of support was done but the answer was: I don't know.
The problem was resolved and I closed the ticket.

If you have the same problem my suggestion is to open a support ticket.
