Subject [jira] [Commented] (SYNCOPE-1017) too many open files (tcp connections)
Date Fri, 17 Feb 2017 16:28:41 GMT

Andrea Patricelli commented on SYNCOPE-1017:
--------------------------------------------

Hi Georg,

I think that this is due to the Syncope Console Java application nature.
I guess that the open files are the compiled sources contained into the .war file of the Syncope
Console application.
I suggest you to increase the max number of (possible) open files on the machine where Syncope
is deployed, like explained in [1], and restart your application server.
