| (2:47:30 PM) skot: Infin1ty: I just did a test on my ubuntu machine and it seems like it takes min(--maxCons, .8*`ulimit -n`) for max connections. | |
| (2:47:51 PM) ajsharp_zz is now known as ajsharp | |
| (2:48:06 PM) Infin1ty: skot, it is, but why does it ignore the mongodb limits in limits.conf? it only works if i set to * or root | |
| (2:48:22 PM) Infin1ty: skot issuing su - -s /bin/bash -c "ulimit -a" mongodb ,shows the correct ulimit | |
| (2:48:50 PM) Infin1ty: skot, looks like the way the init script invoking mongod, so it actually making you set a global ulimit or just for root, which not everyone will like to |
