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?
