[Serusers] Few Questions

Hello, I see some of these errors and warnings in my log file on SER. WARNING: warning skipped -- too big ERROR: t_reply: cannot send a t_reply to a message for which no T-state has been established ERROR: warning_builder: buffer size exceeded How can I get rid of these. Also I had a question on children=4 I know this has been asked before and has been answered. This is what I found online. *"children=4" mean that there will be 4 UDP, 4 TCP and 4 loopback **listenters on your SER, when you start it (you can check with "serctl ps**s" to verify). * Question is does this have any affect on the number of simultaneous calls or sip users etc. Say I want to make sure my system works without any problem for 20K user and 5000 simultaneous calls. What can be pros and cons if I set children to 10, 50 or 100. I will appreciate if anyone can educate me little more on this. Thank you, -Jai
