Hi All, I am using kamailio 5.8.3 as IMS-PCSCF. It connects to PCRF and uses module. It is found that in module cdp, "select" is used in receiving message, which has a limitation in the value for file descriptor. It does not work if the value of fd is greater than 1023. Any idea on how to tackle the case when the value of fd is greater than 1023? Please advise. Thank you. Regards, Hong
