I've not used the Sync Timer in earnest, so I don't know if it has these problems.
Fair enough! I do know that sometimes the 2/80 display can go wrong (I've seen -1/n
!), but the fact that "stop test" is having a problem suggests that there are indeed still some threads active.
Yeah, I've seen that -1 thing too. I've also seen some problems with the webapp I'm testing here were threads get stuck with open ports, sometimes in ESTABLISHED, sometimes in SYNC_WAIT or FIN_WAIT_1. Upgrading to Java5 fixed most of these problems, although it does still occasionally bomb out when it's been under heavy load. I haven't figured out if it's JMeter, Java, the app, network drivers, the switch, or something even more esoteric to blame for this fault. [BTW, Shutdown is a less forceful version - it does not kill threads] Ah, I'll keep that in mind. It might be worth replacing the sampler with a Java Request Sampler
(use a similar time delay) to see how the Sync Timer behaves with a simpler test.
I'll give it a go when I have five minutes. Thanks, Seb! S.
