TCPIP-F-SSH_ALLOC_ERROR, ssh memory allocation error

HP TCP/IP Services for OpenVMS Alpha Version T5.7
on an AlphaServer 800 5/500 running OpenVMS V8.3

But also seen on V5.6 and T5.7 on RX2600 and V5.6 on Alpha

I have setup my SSH clients (Putty for Windows, Putty for Pocket
PC and some other product that I forget now) to do port
forwarding so I can get POP mail and that works fine. But when I
setup port forwarding for PC Anywhere and/or Remote Desktop I get
"TCPIP-F-SSH_ALLOC_ERROR, ssh memory allocation error" in my
TCPIP$SSH_RUN.LOG and the SSH client disconnects. I have doubled
and tripled all quotas for the TCPIP$SSH username. I have also
tried watching the quotas on the TCPIP$SSH process as it dies but
none of the quotas get anywhere near their maximum.

The Accounting information also shows that none of the quotas are
near their maximum values (AUTHORIZE for the TCPIP$SSH account or
PQL parameters in SYSGEN). Does anyone know what is causing this
error and how to fix it?

That may tell someone else something about what you did, but
not me.

Which quotas are "all" quotas? Is the problem with the
TCPIP$SSH account, or the user's account?

Knowing nothing, I'd assume that malloc() failed, so I'd
suspect a shortage of virtual memory (page file quota).

The accounting record for TCPIP$SSH is the one showing the
SSH_ALLOC_ERROR, it also shows in the .LOG for the TCPIP$SSH user
so I think it is not the user's account. At least once I saw the
user's process still around after the TCPIP$SSH process had
already crashed.

First I doubled PGFLQUOTA for the TCPIP$SSH user, then tripled it
then raised it to match the PGFLQUOTA on the user's account
(33554432). Then I raised PQL_DPGFLQUOTA on both the Alpha and
IA64 to 33554432.

Then I increased BYTLM, ASTLM, BIOLM, DIOLM, WSQUO, JTQUOTA and
ENQLM for the account and the related PQL parameters.

So I figured I would give up and see if someone else out here
already solved the problem of using port forwarding to run PC
Anywhere or Remote Desktop and felt like sharing the answer.
