Number of concurrent logins for the same username
Is there a limit to the number of concurrent login sessions I have have that use the same username?
In other words, if I develop a Java application that uses the Web Services API to log into Salesforce, and I run 20 different instances of the application, all logging into Salesforce with the same username, is that a problem? Is there a limit to the number of concurrent sessions that can use the same username?
Thanks!

having different sessions in many instances is fine. I have done this in past on java too. But would suggest, if the login are for same user, try sharing them across java instances via some central cache, this might speed up response time by saving a login() call.
There are no specific limits around the number of sessions, but there are more general api limits including total # of calls, and total # of concurrent calls, so you need to plan accordingly to not run into those.

That's exactly what I was looking for. Thank you!
