Problem with running sybase(2)

mxshao — Thu, 22 Jun 2000 07:13:31 GMT

When the following messages displayed, some other actions happened. As described below:

messages on console and SQLServer errorlog:
kernel Cannot read,host process disconnected

At the same time ,in a continuous ping operation, when Client access DBMS in host, the following message displayed sometimes:
Source quench received.

I wonder why the second message created, and how to resolve it.

Thanks

PROBLEM

Receiving "Source Quench Received" messages on primary network interface.

RESOLUTION

These errors are totally harmless but can be a nuisance if a ping monitor is
being run on the network. There is currently no patch to remove the message but
the change has been implemented in HP-UX release 11.01. It is not known at this
time when 11.01 will be released. In the interim, there are two ways that these
error messages can be suppressed. A single command will take care of them
temporarily or the /etc/rc.config.d/nddconf file can be modified to make the
change permanent.

The following command will suppress the messages until the next time the system
is reset.

# ndd -set /dev/ip ip_send_source_quench 0

A permanent solution is to add the following lines to the file
/etc/rc.config.d/nddconf:

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

Note: Substitute INDEX with a proper value depending on what other entries are
in the file. See the comment in the nddconf file for advice on how to set the
value of INDEX.
