I remember this problem reported/discussed in the past. I don't know why
we didn't note and fix it.

It seems Axis connection objects are reused for a while for the calls
made for same services. I will investigate it further. A workaround/fix
on taverna plugin side for now would be convenient as it is easier to
release the plugin for us and taverna has a god way of updating its
plugins.

Thanks for locating the problem.
