memory issue with jsonrpc - sr-users

11 Feb 2019

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",
