Hi!
-b is the receive buffer of the socket in the OS (for UDP tweaking, I do
not know if this is relevant for TCP), so not related to this problem as
this problem happens inside Kamailio.
Actually 15K is rather small, really strange that you get errors. So, I
did some tests:
1. tcp_rd_buf_size must be increased. The documentation is bad as it
meantions "TCP datagram" but actually means the maximum size of SIP (or
HTTP) message that can be received.
2. tcp_rd_buf_size is internally limited to 16MBytes. If you need more,
you have to change the code in:
tcp_options.c: { "rd_buf_size", CFG_VAR_INT | CFG_ATOMIC, 512,
16777216, 0, 0,
3. If you use real large message you may need to increase the private
memory, and if you forward it with tm module, also the shared memory.
regards

this still does not solve the problem.
I've also tried running Kamailio with *-b 32768* option.
here are the logs:
Jan 2 14:54:24 debdev kamailio[2580]: ERROR: <core> [tcp_read.c:344]:
ERROR: tcp_read: buffer overrun, dropping
Jan 2 14:54:24 debdev kamailio[2580]: ERROR: <core>
[tcp_read.c:1127]: ERROR: tcp_read_req: error reading
Thanks for your help.

Hi,
you may try changing the tcp_rd_buf_size and tcp_conn_wq_max:
http://www.kamailio.org/wiki/cookbooks/3.3.x/core#tcp_conn_wq_max
And since this in development mailing list I'd like to point at what
seem an iaccuracy in documentation: several options refer to the core
parameter called tcp_write_buf, which isn't described in the cookbook:
tcp_conn_wq_max
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.
I hope Daniel or someone who knows reads this..
BR,
Andrew

Hi,
While sending a big TCP SIP message (15K+), I get "tcp_read: buffer
overrun, dropping" message.
this happens after a few fragments have been sent, and then i
get this
message and the connection resets.
is it possible to set the max-buffer size through configuration?
if so,
where?
Thanks, Amit.
