Hi
Our syncope installation has recently crashed a lot (in the end
killing the tomcat container), with errors like this one in Catalina.out:
/SEVERE: The web application [/syncope] appears to have started a
thread named [scheduler_Worker-9] but has failed to stop it. This is
very likely to create a memory leak./

We are still running 0.7 of syncope (yes, I know, I am updating, but
it's a difficult process...)
So my questions:
* Anyone familiar with this error?
* Is it fixed in the modern version of syncope?
* Anybody know of an interim fix for the time being?
Hi Jesse,
this deserves some deep investigation: I'll do and report here.
Thanks for reporting.
Regards.
