Hi,
I noticed a strange behavior on some of our proxy servers, all running Kamailio 5.3.8.
After running for some time (weeks), our monitoring system sporadically starts reporting
errors. The check connects via tls and registers to an Asterisk behind the proxy server.
When this happens, the Kamailio log shows the following line:
ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:1409441B:SSL
routines:ssl3_read_bytes:tlsv1 alert decrypt error
When restarting Kamailio, the problem goes away only to come back after some weeks uptime
again.
On one host, I tried to find something using kamcmd, and I don't know why but I also
issued "tls.reload". And from that point, the monitoring system has not reported
the system as faulty anymore. I repeated the same thing on other hosts when the problem
occured there, all with the same result. "tls.reload" helps. But from the
documentation, I don't know why.
Does anybody have an explanation for it?
Regards,
Sebastian
