JiangHai2011 created an issue (kamailio/kamailio#4610)
### Description
during sipp REGISTER test with the rate 2000cps, there is a low rate to meet
kamailio tcp_read crashes on tls_accept
### Troubleshooting
1.when I set shared memory to 700MB, it is hard to repeat the crash
2.when I use kamailio 4.4.7 version, it can crash on the same point
"sr_ssl_ctx_info_callback "
3.another infomation: both 6.0.5 and 4.4.7 test use the same openssl version
1.1.1w
#### Reproduction
just run sipp tool with REGISTER in 2000cps for a lone time (>12h) and make
sure kamailio service run out of shared memory (in our case, we set -m 300)
