Lots of thigns can cause a telnet session to drop. I would check kernel parameters such as nproc and nfile.

I would run glance or gpm and look at system table usage, you may be running out of space and need to make adjustment.

Attaching some useful sar scrips that can help with the problem.

.rcmd: accept: No buffer space available

Could not be caused by lot of reasons.
Check swap space utilization.
(swapinfo -mat)
Check buffer cache usage.
sar -b
glance -m

What is your setting for tcp_conn_request_max?
ndd -get /dev/tcp tcp_conn_request_max

Hi

Options

1)Network patches

2)Kernel tuning

3)Name resolution
Ip address problems

4)Memory leak

You need to check it - Best bet is a patching update and kernel tuning .

Include maxssiz in calculation
