Hello,

Hi,

it doesn't look like a crash at all, but normal behaviour when message is too large to send. Or are there other log messages you haven't posted here indicating a crash?

Opsss! Sorry! It wasn't a crash, I wrote the wrongly! Indeed it's a normal error log.

You may have to adjust write buffers for tcp -- look at core cookbook, tcp parameters section, and identify the ones with 'wq' in the name.

are you talking about tcp_wq_blk_size or tcp_wq_max? For the first the documentation reports that might be ignored, the latter seems defaulting to 10MB.

Hi All,

I'm playing with instant messaging with a PJSIP client, but as soon as I send body with payload to about 100k I'm getting the error below:

Kamailio is already set with tcp_rd_buf_size=204800

Does anyone can suggest how to fix this?

Thanks in advance, Roberto Fichera.

Mmmhhh! Maybe it's tcp_conn_wq_max ?

Yep! It was! Increased to 200K solved the problem!
