Hi, I have kamailio 3.2 as LCR with many gateways, weights and priorities. Out of no ware It presented this error today: 500 I'm terribly sorry, server error occurred (1/SL). This wasn't happening for all the calls , and was arbitrary. I read on google ,that this error comes form t_relay, so the server was unable to relay the call to the gateway. But all the gateways are reachable and active. The server was on load , almost 30 cps. The same configuration have been running for more than 2 years with any problem. Could these happened for heavy load? I have children=32 in config file. Has anyone an idea of what may happened?
