apache had not fallen first because netscaler is load balancing between 26 web servers and they are already pre-configured for all these heavy load.

- nphase 15y ago26 webservers and only two mongodb instances? Seems stacked.. Why not set up more instances and split the load across them (sharding, splitting collections across replica sets, etc) or similar? Also - big question for me: were you using a ridiculously old version of mongo? I have yet to run into anyone who is on 2.0 or 1.8 and is still running master/slave (as opposed to replica sets). Sounds like your writes weren't working when you moved to replica sets because your client wasn't properly configured.
