Thatīs right Frank,

I have others servers installed AIX 4.3.3 ML10 and bos.net.tcp.client are
4.3.3.81 and I didnīt have the same problem.

On F40 servers where I had the problem bos.net.tcp.client is 4.3.3.75.

Best regards,

Ivo Bernardino.

Hi *,

I think this is a problem only from ML09. The exactly file which the
problem caused is bos.net.tcp.client (from 75-80). Change the no -
parameter is a workaround. Recommendet is to install bos.net.tcp.client
4.3.3.81.

I think you has ML03!?!
But I do not know the problem under ML3.

Best regards,
            Frank Mueller

Hi,

I had the same problem on F40 server AIX 4.3.3 ML09. I open a call in the
IBM
and the solucion was:

Change tcp_pmtu_discover and udp_pmtu_discover parameters with "no" command
to
0:
/usr/sbin/no -o tcp_pmtu_discover=0
/usr/sbin/no -o udp_pmtu_discover=0

The default value is 1.

After that I did this change, the server didnīt have these problems.

Check to see if you are at maintenance level 9 there is a problem in the
tcpip part of maintenance level 9 and causes a memory dead lock. Upgrade to
maintenance level 10 and it will be fixed. I had this happen twice before
IBM analyzed our dump file.
