[Serusers] ser numbers going up

Hi all, Running ser 0.9.6. I notice these numbers going up and never going back down: I am a bit concerened with the red text. Is there any reason why that does not come down to 0. Do I need to restart the ser process once a month or something around that timing? So far I have not heard of any issues with user call setup but I just want to remain proactive. Serctl moni outputs the following: Server: Sip EXpress router (0.9.6 (i386/linux)) Now: Mon Mar 8 10:05:18 2010 Up Since: Fri Jan 8 11:24:17 2010 Up time: 5092861 [sec] Transaction Statistics Current: 1 (176 waiting) Total: 5624219 (0 local) Replied localy: 6049354 Completion status 6xx: 0, 5xx: 121, 4xx: 308504, 3xx: 0,2xx: 5316846 Stateless Server Statistics 200: 13145729 202: 0 2xx: 0 300: 0 301: 0 302: 0 3xx: 0 400: 42 401: 0 403: 0 404: 350766 407: 16536998 408: 0 483: 0 4xx: 2 500: 1 5xx: 0 6xx: 0 xxx: 0 failures: 72 Michael Sabatella IPC Systems Network Services Engineer Office: 1-201-253-2280 Cell: 1-908-380-5321 @ IPCGlobalNetworks.com<http://www.ipcglobalnetworks.com/> ________________________________ DISCLAIMER: This e-mail may contain information that is confidential, privileged or otherwise protected from disclosure.
