<< Previous       unstable work sites

Question: Good afternoon, after moving into your hosting sites there have been no changes, today it was discovered that the last 6 days, the site animalcity.by does not work fully. Users could not post information in connection with the fact that I fell off the mysql server. Error \"PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away: INSERT INTO {watchdog} .......\"It is unacceptable to have a problem with the resource due to a lack of correct MYSQL configuration to such problems we faced. Take action, it is necessary to increase some parameters. http://www.vitalikblog.ru/cms/2009/07/31/mysql-server-has-gone-away-query-insert-watchdog.htmlПо the same reasons, the problem was not reported in the log. Because it could not create the entry.
Answer:

Hello. for the server parameters provide information on the link?  I wish that we would install You the exact same parameters?

Question: I don`t know if it`s 100% to repeat those settings. what is clear is that what the parameters should be increased.
Answer:

Inform what parameters need to be increased. Also, you can do it yourself with root access.

Question: give the current values of these parameters.

Question: the screenshot I gave you to see what the problem is significant. Why again has stopped working mail ? SMTP -> ERROR: Failed to connect to server: Connection timed out (110) we had this situation last time was that the case in your firewall on your side. Why now it cannot connect via SMTP ? what has changed in your setup VPS 7-8 March ?
Answer:

what kind of email is it? what \"our side\" ?

please do not mix in one ticket different problems. you started about mysql ? let`s first deal with him. soobshaet which a sample of the log You make.

 

Question: you know that in the log there is a date ? I was asked to do a sample by date for today, let`s see in what format the date is displayed in the logs and mysql give me a sample of all rows where date is today`s. the second not less important question, did you make/made changes to firewall settings, there`s information in the other ticket, this was done to set up email, now that email is not working, probably I have not worked the site for almost a week. So check why the site does not connect via SMTP - timeout.
Question: and I would like to leave feedback about your work to your leadership.
