I'm not sure that these errors are related to the users. Anyway, I ended up not using that feature since it didn't really fit my needs. What I did is to extract the thread number from my Java sampler and deriving the user name and password from the it (.e.g. thread1 --> user1/pass1). I did it with the following code:
String threadName = Thread.currentThread().getName(); int pos = threadName.lastIndexOf('-'); String userIndex = threadName.substring(pos+1); Hicham -- View this message in context: http://www.nabble.com/CSV-Data-Set%3A-Assignement-of-users-to-threads-wrong-when-ramp-up-time-%3E-0-tp19793575p20065849.html Sent from the JMeter - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
