Following are the steps we done on Alim Server:

  • Checked Alim DB and size comes around 1.3GB

    -> du -hs alim_07_03_20.13.sql
    1.3G alim_07_03_20.13.sql

When we checked table that took too much space is ajaxtracking (319M) and boomerang_beacon (366M). We truncated these these table and also dropped unwanted tables from Alim Database. Now the size gets dropped to 458M.

-> du -hs alim_07_03_20.13_new.sql
458M    alim_07_03_20.13_new.sql

Command used to truncate a table:

mysql> truncate table ajaxtracking,boomerang_beacon;
  • Stopped AIDE:

Temporarily stopped AIDE script.

  • php5-fpm configuration:

Changed pm.max_requests (The number of requests each child process should execute before respawning) from 200 to 0 (unlimited)

Then changed pm.max_children (This value sets the limit on the number of simultaneous requests that will be served)from 7 to 5.

With this setting we have tested accessing alim site with ab command. Now it seems stable in which load increases slightly only and its not overshooting.
