SNAT pool Inet port exhaustion
We are running XMPP application and we have 500k users so in short 500k TCP persistent connection and total 4 XMPP servers, based on math i created 15 ips SNAT pool (assuming 15 ipaddress are enough for 500k tcp connection) but somehow i am still getting error "Inet port exhaustion" in /var/log/ltm
Apr 13 17:57:23 lb-a warning tmm1[12866]: 01010281:4: Inet port exhaustion threshold reached on 10.0.0.61 to 10.10.10.149:5222 (proto 6)
Apr 13 17:57:24 lb-a crit tmm[12866]: 01010201:2: Inet port exhaustion on 10.0.0.68 to 10.10.10.224:5222 (proto 6)
Question is how many connection single SNAT IP can make to servers?
