Hello Respected Sir,
I am using OLS and aapanel on my server. I observed some times my site goes offline and when I opened my site it was showing "Error 503 Connection Closed"
Then I checked my STDERR.log and found tons of these below error:

"" Reached max children process limit: 10, extra: 3, current: 13, busy: 13, please increase LSAPI_CHILDREN. ""

So @aaPanel_Jose Can you please suggest me how to increase LSAPI_CHILDREN?

    Paul
    I also encountered this problem and did not find a clear solution after searching on the OLS official website. . I will continue to pay attention to this matter, if you have any progress, please post here

      can you please check if you have file exits on your server then edit and find PHP_LSAPI_CHILDREN 10 to require number
      /usr/local/lsws/conf/httpd_config.xml

        JAY Yes I edited this and restarted ols. Still same errors are coming in STDERR.log in SSH. This did't fix my problem.

          sorry it looks

          cat /usr/local/lsws/conf/httpd_config.conf | grep LSAPI_CHILDREN
          PHP_LSAPI_CHILDREN=10
          or
          cat /usr/local/lsws/conf_bt/httpd_config.conf | grep LSAPI_CHILDREN
          PHP_LSAPI_CHILDREN=10

            JAY As I said, I have edited it. But it didn't solve my problem.

              change MaxConn too and try

              Dear Jay bro, I have changed it too. It worked for some hours. Then again same error started coming.
