[SR-Users] memory issue with jsonrpc

Hi, I'm hoping someone can guide me in the right direction. In kamailio 5.2.1 I'm getting the following memory errors after a while (hours or days) of sending messages with jsonrpc. Restarting kamailio clears them for a while. Any suggestions on what I should change, or how to better identify the issue? 24(6177) ERROR: <core> [core/mem/q_malloc.c:291]: qm_find_free(): qm_find_free(0x7f1cbe6fd000, 5712); Free fragment not found! 24(6177) ERROR: <core> [core/mem/q_malloc.c:425]: qm_malloc(): qm_malloc(0x7f1cbe6fd000, 5712) called from tm: h_table.c: build_cell(339), module: tm; Free fragment not found! 24(6177) ERROR: tm [uac.c:422]: t_uac_prepare(): short of cell shmem 24(6177) ERROR: pua [send_publish.c:700]: send_publish(): in t_request tm module function 24(6177) ERROR: pua_rpc [pua_rpc.c:280]: pua_rpc_publish_mode(): pua send_publish failed I have these buffer values in the config file tcp_rd_buf_size=65536 pv_buffer_size=32768 and I'm running kamailio with these memory options "-m 1024 -M 16" The jsonrpc message I'm sending look like this { "jsonrpc": "2.0", "method": "pua.publish", "params": [ "sip:172.1.1.3:5060;transport=tcp", "300", "reg", "application/reginfo+xml", ".", ".", ".", ".", "<?xml version='1.0' ?> <reginfo state='partial' version='0' xmlns='urn:ietf:params:xml:ns:reginfo' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'> <registration aor='sip:55555@uw.edu' id='a19685' state='active'> <contact duration-registered='906' event='registered' id='c19685--1732979172--1829864152-2' q='1.0' state='active'> <uri>sips:55555@172.1.2.4:62270;transport=tls;avaya-sc-enabled</uri> <elin></elin> </contact> </registration> </reginfo> " ], "id": 1 } Thanks, -Ben
