Hello, I am looking for a mysql expert. I have a problem with a LAMP server hosting a drupal website. The mysql service often freezes and the website displays an error connecting to the database: PDOException: SQLSTATE[08004] [1040] Too many connections in lock_may_be_available() When trying to restart mysql with "systemctrl restart [login to view URL]", the service will not stop and I have to kill it with "kill -9 <pid>". I am looking for someone to adjust the mysql configuration to stop this from happening. Can you give me a quote please?

Ok.. Look. This problem is complex. This error doesnt give any info about what happen instead of one fact - Your site uses mysql database too many times. The simple solution is reconfigure Your server to use more connections - i can do it. But probably it isnt full or best solution. We can try but it will not 100% resolve problem Better solution is analyze what exact Your site does with Your database and create some optimizatons. For now i dont know wich exact - i must research and to do many work to understand it First of all - wich CMS You use? I will need 1- root access to server 2- some time 3- we will discuss possibilities we have after ill research My price for simple solution (optimizing mysql configurations) - is just 100 euro. So if You want i to do only this task - please say me it before admit task to me so i will not pay for this project big commission in case You want i to do a deep analytics - it will take more time and i cant say now full price but it will be minimum 200 euro. So - lets chat.

Hello, The problem you are describing could be multiple things. Maybe it is better to have a look at the application and its configuration with the database as it is not very common to have this type of problems. It could be better to solve the issue from an application perspective because you can increase MySQL limits but if it is an application issue the problem should arise again with more users. That's my point of view. If you want me to try to solve from that perspective contact me. Regards
