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
