Re: UCX memory problem on VMS
if you would like help from this forum, please be very specific about the operation/command performed and the exact error message returned.
The commands UCX SHOW COMM and UCX SHOW COMM/MEM display information about UCX-specific memory.
SHOW MEM/POOL/FULL displays information about the OpenVMS nonpaged pool.
Consider to include the output of the above commands in a text attachment to your next reply. Capture this memory information at a time where everything is working and at the time of (or immediately after) the error.
Volker.

Re: UCX memory problem on VMS
the counters look o.k. - the peaks have not reached the maximum values and there are no waits or drops.
You did not provide the SHOW MEM/POOL/FULL output for nonpaged pool.
If the system crashes (and you have got a valid SYSDUMP.DMP file), please provide the contents of the file CLUE$OUTPUT:CLUE$LAST_node.LIS (summary of system crash data). Getting the UCX memory data from a VAX dump might be hard...
You can look at the nonpaged pool data in the dump with:
$ ANAL/CRASH SYS$SYSTEM:SYSDUMP.DMP
SDA> SHOW POOL/NONPAGED/SUMM
and look at the amount of pool used.
Volker.

Re: UCX memory problem on VMS
your OpenVMS VAX V7.1 system has incurred a HALT restart crash. The HALT-PC seems to be A67EB, a P0 address in current image DKA100:[AGMS.MCSYS.][IMG]SYSIPC.EXE;56 - the PSL shows: Kernel Mode, IPL 0 (i.e. process context). You can examine the failing instruction with SDA:
$ ANAL/CRASH SYS$SSTEM:SYSDUMP.DMP
SDA> EXA/INS A67EB
SDA> EXA/INS A67EB-20;30 ! instr-stream
This type of crash happens, when a HALT instruction (HALT = 0x00) is executed in kernel mode. OpenVMS itself does not use HALT instructions to signal problems, it will always uses BUGW or BUGL to initiate a crash. Some application programs may use a HALT to signal a problem. A HALT can also happen, if the program counter (PC) ends up pointing into a data area instead of into an instruction stream.
There have been no nonpaged pool expansion problems before (PMS$GL_NPAGDYN* = 0).
If this system has crashed in the same way before, you can look at the crash history with:
$ CLUE:==$CLUE
$ CLUE/DISPLAY
CLUE_DISPLAY>DIR
If there have been HALT crashes before, look at their CANASTA parameters with CLUE_DISPLAY> n (n= crash # from column 1)
and look for the name of the current image.
Also look at CLUE_DISPLAY> SHOW STACK n for the failing PC/PSL for those HALT crashes.
Please report your findings here.
