[SR-Users] tls + tcp problems

Hi, I am experiencing two problem: First: I am experiencing that tls read buffer overflow, if i use default value of tcp_rd_buf_size If i doubled the size of read buffer and i use tcp_rd_buf_size=8192 then the problem seems to be solved. Second: I am experiencing that TLS connection is dropped by sip proxy very frequently! And i think the tcp connection shouldn't dropped! So my guess is that TLS communication is not restarting the timeout counters! So in every 2 minutes the sip-router is restarting the TCP connection with tcp RST. like this: Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [tcp_main.c:4304]: tcp_main: entering timer for 0xac537c74 (ticks=446299809, ti meout=446299809 (0 s), wr_timeout=0 (240541717 s)), write queue: 0 bytes Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [tcp_main.c:4346]: tcp_main: timeout for 0xac537c74 Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [io_wait.h:617]: DBG: io_watch_del (0x824cf80, 48, -1, 0x10) fd_no=41 called Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: tls [tls_server.c:597]: Closing SSL connection 0xac4a0374 Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [ip_addr.c:247]: tcpconn_new: new tcp connection: 10.10.10.10 Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [tcp_main.c:1081]: tcpconn_new: on port 36142, type 3 Sep 5 11:28:48 hal /usr/sbin/kamailio[8129]: DEBUG: <core> [tcp_main.c:1382]: tcpconn_add: hashes: 2473:3781:3367, 5 This second problem is not solved and very urgent for me. Any help suggestion is highly appreciated! Thanks, Misi
