Folks,
I have set up an application using Cradle 0.6.4 connected to CouchDB 1.2.0, and
started stress testing it... and encountered an issue.
After setting up a simulated load -using nodeload- of 60 users each requesting 100
documents of about 60MB (they vary from a few bytes to 60MB, but most of them are
60MB) I found out that some connections to CouchDB were not closed after the load
program terminated.
I have set the maxSockets parameters of both http module and Cradle to 50, hence
the app ramps up to 110 open connections, then the number of connections
decreases... but some of them remains in an "ESTABLISHED" status.
Here's the netstat output:
tcp 5896064 0 127.0.0.1:37968 127.0.0.1:5984 ESTABLISHED 31914/node
tcp 6051609 0 127.0.0.1:37977 127.0.0.1:5984 ESTABLISHED 31914/node
tcp 1095733 0 127.0.0.1:37947 127.0.0.1:5984 ESTABLISHED 31914/node
tcp 1590408 0 127.0.0.1:37949 127.0.0.1:5984 ESTABLISHED 31914/node
All of them are connections from my app to CouchDB: is there any way to prevent
this or -failing that- force a periodic closing ?
