MaxClients Ubuntu stops responding
Hello, I'm running a site on 512MB 20GB 1TB Ubuntu LAMP droplet. Its average 25-60 concurrent visitors all day. It's working normally some time 4 -5 h then in moment no free memory, apache stop responding and site is off. I set swap file 1GB and swappiness=10 and when its working normally with free -m I see that there is about 160MB physical memory free and whole swap file. I think that problem is with MaxClients in apache2.conf , and I'm not sure what values to set. I see that max value is 256 for this server. What will be the optimal settings?
