Looks like the database (MongoDB) is not running. AirMatch uses that to store data. You could check the mongodb:
(MM01) *[mynode] #show netstat | include 27017
u_str LISTEN 0 0 /tmp/mongodb-27017.sock 173728929 * 0 users:(("mongod",pid=24012,fd=19))
tcp LISTEN 0 0 127.0.0.1:27017 *:* users:(("mongod",pid=24012,fd=17))
tcp ESTAB 0 0 127.0.0.1:50496 127.0.0.1:27017 users:(("python",pid=6707,fd=3))
... then the line with LISTEN and 127.0.0.1:27017; so third line in this example. Every process can potentially crash, but it's not expected, so it may be good to open a TAC case. This is nothing that an end-user should be aware of, in fact, it's the first time I see that this process is running, never bothered as it just works. You could also just reboot your MCR/MM, and see if the process comes back. You can also restart the mongod process: "(MM01) *[mynode] #process restart mongod"; but if it stopped there is probably a reason that needs to be found to prevent the same happening time after time.

Subject: Airmatch error - couldn't connect to server
I'm trying to view some airmatch info via cli, and I'm getting the following error:
Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:147
I get this trying to run:
show airmatch optimization
show airmatch solution ap-name <ap-name>
...and other cmds.
Airmatch should be running, as it appears enabled:
(conductor) [mynode] # show airmatch profile
AirMatch profile
----------------
Parameter Value
--------- -----
schedule Enabled
deploy-hour 5 AM
quality-threshold 8 percent
Couldn't find anything of note in the conductor logs.
Any ideas on what I could check? Are there processes I could check? Can the airmatch module crash? Thanks for any ideas or direction.
