scope and glance - resource allocation issue

Hello,

There is a strange problem where I want to check resource utilization with glance but it directly creates a core file and OVO SCOPE process isn't running on the server although I have stopped and started it several times. It gives a bad allocation message where there is enough memory&swap space and parameter usage seems fine (i checked the forum and encountered http://community.hpe.com/t5/Languages-and-Scripting/aCC-runtime-error/m-p/4287919/highlight/true#M43448) Could it be a known bug or anything you would suggest to investigate in core file?

What is the value of maxdsiz_64bit?  You need to grow by 4 Gb.

 
maxdsiz_64bit XXXX / 2147483648

 

This is less than half the needed size.  (The proper command is kctune(1m)).

I also have other HPUX 11.31 servers running glance with that setting of maxdsiz_64bit. How did you understand that it is less than required?

So it started again; after killing midaemon process. mwa stop; mwa start action apparently didn't kill midaemon process. That was the solution, the cause is still unknown. It still may occur.

Because it failed?  :-)  Because (0xffffff30 bytes) is near 4 GB.

Of course I don't know why it needs so much.

Hmm, since scopeux is a 32 bit app, 0xffffff30 is really a negative number so likely to be a software bug.
