The old CSC Sydney site shows release notes for ECO 5 (no kit link), but the last version that I can find on the itrc site is ECO 4.

ftp://ftp.itrc.hp.com/data/archived_patches/openvms_patches/axp/6.X/v6.1/ucx/4.2/

From the ECO 4 release notes:-

ECO Z 25-JUN-1999 Alpha and VAX

Images:

UCX$BGDRIVER.EXE UCX V4.2-21Z
UCX$INTERNET_SERVICES.EXE UCX V4.2-21Z (VAX)
UCX$INTERNET_SERVICES_SEC.EXE UCX V4.2-21Z (VAX)
UCX$INTERNET_SERVICES_V6.EXE UCX V4.2-21Z (VAX)
UCX$INTERNET_SERVICES_V6_SEC.EXE UCX V4.2-21Z (VAX)

Problem:

UCX small buffers are never deallocated when creating and
deleting SLIP interfaces (actually any multicast-capable
interfaces). After some days the max value is reached.

Solution:

Deallocate the multicast address buffers that get
allocated each time an interface is defined.

Reference:

PTR 70-5-676 / CFS.57541 / EVT102495

Maybe not applicable?

Steve,

the no. of sockets used is certainly reason for concern. Does UCX SHO DEV show lots of BG devices ? Still with active connections ? Which processes do they belong to (SHO DEV/FUL BGxxx) ?

Steve,

is this a 'deja vu' event ?

See:

http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=826950

from 3-MAR-2005. If this is the same system, you were at 300 sockets at that time, now you're at 900.

More than just a coincidence ?

Volker.

Steve,

I see there is 'wait' in your small buffer.
so you have increased your small buf to 2000 max.
After this (stop/starting telnet service) have you seen ucx show comm/mem?.Make sure there is no 'wait', if there is any wait, that means still you have exceeded your small buffer, so you have to increase small buf value more.
