The use sec property is commented out so it should default to false...

This is the last thing that gets logged before it locks up:

Do you have the shared editing context enabled? The last time someone had a locked with remote sync was with SEC enabled. I only run with SEC turned off, so it's just never been tested with SEC hanging around.

Hi,

We have two jmeters scripts one that creates objects, and one that modifies them. Both scripts interact with two instances, everything works as expected with no lock ups. However as soon as we enable remote synchronization one instance locks up. The only way to get rid of the locking is to either simulate the loading on one instance with the other just listening to the changes or to turn off remote-synchronization all together. Any help would be greatly appreciated.

Thanks,

Saad
