Subject Re: ARTEMIS: bad-performance behaviour after 7-10 days of usage
Date Mon, 13 Feb 2017 11:46:23 GMT
Hi Francesco,

Thanks for the Thread dump.  I think I know what the issue is, I'll get it
fixed today.  This fix won't make the 1.5.3 release but I can provide you
with another snapshot with all the required fixes.

We can try to do another revision release soon after including this fix.

Cheers
Martyn
