freezing Ports under ARIES
We recently changed to Itanium Servers and havn't had the time to port all applications.
Therefore we need to run a Vantive Server under Aries to use the old binaries from HPUX 8.11.11.
Our Problem is, that if we have to reboot the vantive server the used Port will stay blocked and we only have the chance to give it free
by rebooting the whole machine, or we have to use another Port.
We changed parameter socket_msgeof as recommended but this was not the final solution, was still have to procceed as before.
I cannot imagine, that rebooting the whole Machine should be the only solution to unblock these Ports.
Does anyone else also realized such Problems by using ARIES or does anyone have an idea how we can free the Port without rebooting until we redeveloped?
Sorry if this is a redundant Post, didn't find one.
thx
Raphael

Re: freezing Ports under ARIES
what is your current version of hpux?
Did you update patches on your system?
There is no reason why aries could block your port. It is more probably an other problem.
You probably should contact hp support.

Re: freezing Ports under ARIES
Aries also introduces an average performance penalty of 70%.
Have you considered porting the software and recompiling?

Re: freezing Ports under ARIES
Can you use lsof to find who has the port open?

Re: freezing Ports under ARIES
actually we run under HPUX 11.31.
We tried o analyze via tusc and lsof but the problem is, that there is not longer a relation between any proccess and the blocked socket so we got no helping info from tusc or lsof, we only see that the port is not usable.
The Problem is, that users connection over vantiv iw server will be closed before logouts are completely performed and we have to restart the server from time to time.
In the past, there were no outstanding
close waits on sockets. Now under itanium and aries we see these close waits without active procceses on these sockets.
We work on Porting the Applications but a workaround until this is done would be perfect.
Recommandation from HP Support is to set the socket_msgeof active, we allready did it, but we still have the Problem.
Many thanks for your posts!!

Re: freezing Ports under ARIES
we have exactly the same problem at our customer, same application, same frozen sockets which can only be released by reboot.
Also the circumstances are the same, CLOSE_WAIT ports without processes paired to them, all this happening after migration from 11.11 to 11.31.
Before migration everything was fine, now we have a case at HP open which has already been escalated to level 3 (with coredump sent for analysis). Until now, we have no workaround (the case exists since 6th of August).
We also tried to get some support from the forums in:
http://forums13.itrc.hp.com/service/forums/questionanswer.do?threadId=1362565
Once we'll get a real result from HP support, I may share the info.
