Hi, Juha This issue is discussed here https://github.com/kamailio/kamailio/pull/1376
As temporary solution i use jsonrpcs fifo for big results. For example cat /tmp/kamailio_jsonrpc_reply_fifo > lastcontact.dump & echo '{"jsonrpc": "2.0", "method": "htable.dump", "params":["last_contact"], "reply_name": "kamailio_jsonrpc_reply_fifo", "id": 1 }' > /tmp/kamailio_jsonrpc.fifo

I tried to issue mtree.list command using xmlrpc query that would result in large response, and got error

I though that perhaps I could get rid of the error by increasing value of core var tcp_conn_wq_max. Description of the var tells:
Maximum bytes queued for write allowed per connection. Attempting to queue more bytes would result in an error and in the connection being closed (too slow). If tcp_write_buf is not enabled, it has no effect.
What is tcp_write_buf and how to enable it? I could not find anything about it in core cookbook.
