Hello,

you can see tcp write queued bytes with:

kamctl rpc core.tcp_info

If you have an older version, do kamcmd core.tcp_info

It may be also the OS queues that are busy, if the other side is not not reading fast, look at netstat output for Send-Queue in:

netstat -altp

Cheers,
Daniel

Thanks Alex for your response. I honestly forgot about these parameters and will play with them a bit.

Is there anyway to log how much is written or stored in the buffer?

Hello,

Could it be that your send queue or other parameters regulating outgoing
flows are too low?

Stuff like this:
