It looks like you're occasionally reaching the max_children setting per the 5 minutes of the log file you sent:

Hi @Nirjonadda

When this occurs what's the memory usage like on the server? You can view current memory usage with:

Code:
free -m
or historical memory usage for the last 12 hours with:

Code:
sar -r
