Reached max children process limit: 2, extra: 0, current: 2, busy: 2, please increase LSAPI_CHILDREN

Question

We are using 2 lb + 2 api's + 3 mysql for running our burger website. During peak order time website get slow and some time not available. We have checked the logs in detail and we could see the below in API litespeed error logs

[STDERR] [24627] Reached max children process limit: 2, extra: 0, current: 2, busy: 2, please increase LSAPI_CHILDREN

We have tried raising the LSAPI_CHILDREN and other limits via litespeed admin url meanwhile the setting is not getting affected on back end. We get the same error again, when we have tried api cluster restart the settings are again reverted to the same.

I am attaching the screen shot of the changes we have done, the above error log is continuously logged after the change and litespeed restart. Due to continuous down issues we are moving to nginx for now. We need a proper solution for this so that we can use litespeed again.

Answer 1

You may use (add & set) the variable LSWS_MAX_CHILDREN in the LSWS layer (in your case) or in LLSMP layer (in case when LLSMP layer is used) to set the maximum children process limit for the server via the Dashboard.
The variables list access

Add and set the variable

Restart is required to apply changes.

To ensure the best operability, Jelastic sets this value equal to the number of available CPU cores (by default) and due to it this variable is not visible in the variable list. For more details, please follow the link LiteSpeed Web Server.
