Hi
It is difficult to suggest why an array is written OK in some cases but
not in other cases when the concurrency is high, my immediate thought
that may be the application data are being updated concurrently too
which has some side-effects on the write process
Cheers, Sergey

Hi,
Hopefully this is the right mailing list.
I am having some trouble with CXF inside Karaf.
Sometimes, when the same REST is invoked concurrently at the same moment I
see the following exception in my log files:

The next REST invocation after this exception gets a random response, from
an unrelated REST method. Also there are timeouts when invoking REST
methods.
I would really appreciate some help with this issue, as aim out of ideas on
this one.
