[SR-Users] Large Content-Length crash with instant message

[Daniel-Constantin Mierla]

Hello,

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?

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.

Cheers,
Daniel
