Hi!

I did several and several tests and I don't know how to proceed anymore.

I have a webserver using aaPanel + OLS v. 1.6.5. Everything works perfectly. My problem appears when I need generate SSL certificate. I realize that when I generate a certificate for a new website, the server load goes up considerably.

Using the top command, I realized that when a new certificate is generated, several lsphp processes are created, which causes high server usage.

I also realized, testing in another vm, that this problem does not happen when the number of sites using php on the server is small (I took a snapshot of the server, excludes all websites and left only one with php).

Has anyone had a similar situation?

Thanks in advance!

Hi,

sorry for the delay, I only saw the answer now.

answering your question: no. It create several processes when I perform other tasks as well, such as:
- Add Site;
- Enable / Disable write access log;
- Enable / Disable redirect;
- Generate SSL;
- Force HTTPS;
- Disable / Delete SSL

I opened the same topic in a more detailed aaPanel forum. I will add the other details here. thanks for listening!

Hi,

I deepened the research!

I found out that OLS controls, through the configuration file, the maximum number of processes that can be created, reference below:

https://openlitespeed.org/kb/troubleshooting-too-many-lsphp-processes-on-da-when-using-ols/

I added the settings, and confirmed through the OLS, panel that they were read by him.

But, the lsphp continues to generate several processes = (

Perhaps this configuration should be done elsewhere, in addition to the main file, to be read and executed correctly by aaPanel.

I also noticed that this same behavior (creating several processes) appears with other operations such as:

- Add Site;
- Enable / Disable write access log;
- Enable / Disable redirect;
- Generate SSL;
- Force HTTPS;
- Disable / Delete SSL

I hope the information is useful, and I am available for any necessary simulation or testing

Thanks!

Right,

unfortunately, it would take a very long time for me to migrate all sites to a server with cyberpanel and perform the tests.

From the tests I did, this high process load only appears when there is a large number of sites inside the server using php. So I believe there may be some configuration within the files.

extprocessor clientwebsite.com {
  type                    lsapi
  address                 UDS://tmp/lshttpd/clientwebsite.com.sock
  maxConns                20
  env                     LSAPI_CHILDREN=20
  initTimeout             600
  retryTimeout            0
  persistConn             1
  pcKeepAliveTimeout      1
  respBuffer              0
  autoStart               1
  path                    /usr/local/lsws/lsphp74/bin/lsphp
  extUser                 www
  extGroup                www
  memSoftLimit            2047M
  memHardLimit            2047M
  procSoftLimit           400
  procHardLimit           500
}

Can you tell me what these parameters do?
- maxConns
- LSAPI_CHILDREN

Can changing these parameters decrease the amount of processes created by lsphp?

Thanks for your attention!

Yes,

The peak of memory occurs only when I do one of the above actions.
In normal operation, memory usage is very low (1.2 GB of 4 GB).

This is actually the only critical problem I had with aaPanel. And it appears only with OLS, using Apache and Ngix the memory peaks do not occur.

Again, thank you for all your attention!

If you have another virtual machine, I would install cyberpanel and see how it compares. It is completely free (and unlimited) as long as you choose OpenLitespeed as the webserver.
