[SR-Users] secure websocket error in kamailio

Hi All, I am running the kamailio for secure websocket (WSS). While running traffic testing the kamailio is not able to take beyond 2300 connection. I am getting below error. 45(12831) ERROR: tls [tls_server.c:243]: tls_fix_connection_unsafe(): tls: ssl bug #1491 workaround: not enough memory for safe operation: 208 45(12831) ERROR: sl [../../forward.h:247]: msg_send(): tcp_send failed 45(12831) ERROR: websocket [ws_handshake.c:113]: ws_send_reply(): sending reply 46(12832) ERROR: <core> [tcp_main.c:3577]: handle_ser_child(): received CON_ERROR for 0x7f03e0b0fa18 (id 651), refcnt 3, flags 0x4018 45(12831) WARNING: <core> [tcp_read.c:1642]: handle_io(): F_TCPCONN connection marked as bad: 0x7f03e0b0fa18 id 651 refcnt 1 44(12830) ERROR: tls [tls_server.c:154]: tls_complete_init(): tls: ssl bug #1491 workaround: not enough memory for safe operation: 304 44(12830) ERROR: <core> [tcp_read.c:1326]: tcp_read_req(): ERROR: tcp_read_req: error reading I have seen below data in kamailio at the time of getting error. shmem:fragments = 57 shmem:free_size = 16986416784 shmem:max_used_size = 193649976 shmem:real_used_size = 193452400 shmem:total_size = 17179869184 shmem:used_size = 188516920 Could you please suggest me how can I get more performance from kamailio while using WSS ?
