UNIX socket in HP-UX 10.20 : socket overload condition

[Thomas Pohlen]

Hi all,

i get the following message in my application log:

"The socket is overloaded"

some time later

"Overload condition has abated"

The default buffer size is 64k for TCP and UDP Sockets and my application is using 96kb buffer size.

How can i check if have have enough space for sockets , where is the limitation in HP-UX 10.20 ? Is it the FS size ?

Thanks in advance

Windows and perhaps some other OS's don't do the right thing according
to
HP when receiving source quenches, you can disable it by turning this
feature off with

ndd -set /dev/ip ip_send_source_quench 0

and edit

/etc/rc.config.d/nddconf

and add

TRANSPORT_NAME[0]=ip
NDD_NAME[0]=ip_send_source_quench
NDD_VALUE[0]=0

and replace the instance number with the correct one, if this is
your only parameter '0' is the only correct one. Editing nddconf
will make sure this feature doesn't get turned next time you
reboot.
I think in 10.20 you can see neptune beaucouse ndd is of 11.00.

nettune -s /dev/ip ip_send_source_quench 0

For 10.X, nettune changes do not do not survive reboots! Create a startup file in /sbin/rc2.d typically /sbin/rc2.d/S341nettune that runs the nettune(s) that you need.

The application is written for unix and i do not want to set logging off.

The info i get is only COMMS_INFO and no error.

Kind Regards
