### Description <!-- Explain what you did, what you expected to happen, and what actually happened. - we migrated rtpengine urls from udp to websocket, so that kamailio is communicating to rtpengine overwebsocket to manage the offer and answer. however we observed that, tcp reciever process is consuming pkg memory as, traffic increased, but when traffic is idle then its not getting freed automatically. and eventually its consume all memory. - - --> ### Troubleshooting - as checked further we particulartly tcp reciever process was consuming pkg memory , then further we checked from corex pkg_sumary for that process id, and found that rtpengine: rtpengine.c: send_rtpp_command was consuming highest memory. #### Reproduction console rtpengine url with ws endpoint. <!-- If the issue can be reproduced, describe how it can be done. --> this is reproducible, we can configure websocket in rtpengine module and then we can initate calls. and increase the number of calls over the period of time #### Debugging Data <img width="1399" alt="Screenshot 2024-03-06 at 4 30 16 PM" src="https://github.com/kamailio/kamailio/assets/115363081/0904892e-6a… kamcmd pkg.stats entry: 24 pid: 378355 rank: 17 used: 7467640 free: 24348320 real_used: 9206112 total_size: 33554432 total_frags: 66 desc: tcp receiver (generic) child=0 kamcmd corex.pkg_summary pid 378355 Mar 6 16:31:52 coreproxy-4 /usr/local/sbin/kamailio[378355]: ALERT: qm_sums: qm_sums(): count= 8075 size= 4638760 bytes from rtpengine: rtpengine.c: send_rtpp_command(3040) ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` (paste your output here) version: kamailio 5.7.0 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled on 01:04:28 Jan 25 2024 with gcc 9.4.0 ``` * **Operating System**: <!-- Details about the operating system, the type: Linux (e.g.,: Debian 8.4, Ubuntu 16.04, CentOS 7.1, ...), MacOS, xBSD, Solaris, ...; Kernel details (output of `lsb_release -a` and `uname -a`) --> ``` No LSB modules are available.
