Hi, 

one of the users have been using his pos session for over a month now without closing it. When he tries to close it he is getting the below error:

Traceback (most recent call last):

    raise Exception('CPU time limit exceeded.')

The server is a VM with 4 vCPU and 8 GB of RAM

the conf is as follows

xmlrpc_port = 8069

max_cron_threads = 1

workers = 9

limit_time_cpu = 600

limit_time_real = 1200

limit_memory_soft = 2097152000

limit_memory_hard = 3145728000

Any idea how to close this pos session ? Any help will be realy appreciated. 

Regards.

Rony
