UCX RWAST state

[Phil Mather]

Hi,
VMS 7.1 UCX 4.2
Over the last week or so I have encountered the UCXTNS Telnet symb in an RWAST state along with a few user processes.
To clear this, I have rebooted (Alpha 4100) but wanted to knkow if there is any investigations I could do to find the root cause.
Any advice appreciated.
Regards,
Phil Mather

You can apply the Eco 5 of Ucx 4.2

I guess your rwast is just a depletion of quota problem.

It may help to see the output of
ucx sh comm
ucx sh comm/mem

and use pquota to see which quota is too short for this telnetsym process

pquota is availbale at
http://h71000.www7.hp.com/freeware/freeware40/pquota/

just copy pquota to you sys$login, define
$ pquota :== $ sys$login:pquota

and do
$ pquota 241
to monitor the process with the pid of 241

Did you do a forced crash?

Phil,

You may be knwon this, generally a process will endup with RWAST state either in one of this situation...

Process is waiting for the deletion of a sub-process
AST Limit has been exhausted (ASTLM)
Direct I/O Limit has been exhausted (DIOLM)
Buffered I/O Limit has been exhausted (BIOLM)
Process is waiting for outstanding I/O to complete

But you mentioned there are other processes too in the same state, what are all other process?

The following article is quite old, but still makes a good starting point into RWASTs:
