Hi, It seems that the JNDI interface is not closing the connections. It seems that this is a (un)known feature of the javax.naming package, as it seems to happen as wel with other jndi packages.
So it's not related to jMeter. (unless you know a way to "manually" find out information about a socket and close that somewhere in the code) (i'm using the extended ldap sampler) Dolf -----Original Message----- From: sebb [mailto:[EMAIL PROTECTED] Sent: Thursday, July 07, 2005 12:51 To: JMeter Users List Subject: Re: Problem with connections On 7/6/05, Smits.Dolf <[EMAIL PROTECTED]> wrote: > Hi all, > > Im running Jmeter on a local machine, generating a severe load on the > server. > The tests fail because the server is getting to much connections. > > I use a thread group, existing of 95 threads. > The thread group contains a loop controller which loops 100 times.

The existing samplers work on the request-response principle, and a thread will not continue until the sampler has read the response (or it timed or or failed etc). > OR, wil the loop send out all requests as fast as possible, without waiting > for responses?

Not sure how the LDAP Sampler handles connection closure/re-use.
