Can anyone shed any light on gma errors

[David Lockwood]

Every couple of weeks some of my users get a gma_more_core-> mmap failed Not enough memory error message. The error is produced whilst the user is running Catia V5. Once the error has occurred once then it can be repeated easily until the machine is rebooted. We are using HPUX 11.11v1. On the face of it it looks like a memory issue but when I run glance while the user reproduces the problem I can still see 500Mb of free user memory and only 15% swap utilisation. When the error occurs a file called gma_heap_0x3a001b60 is created in /tmp.

Can anyone shed any light on the gma_more_core error and the gma_heap file ?

Thanks
David

Hi David,

Couple of things:

1) What does reserve show in a swapinfo -tam output? It's possible that you exhaust all the reserve space in swap. All processes have to put a "placeholder" in swap before they can stop.

2) Do you have swapmem_on = 1 in the kernel parameters? That'll allow you to use approx 75% of system memory as pseudo swap.

3) Check your shm???? kernel parameters - you may be hitting a shared memory limit.

4) While you're at ir check the max?siz (max?siz_64bit IF this is 64 bit SW) you could be hitting a ceiling there as well.

HTH,
Jeff

Of course that should be

"....before they can start."

Hi


Do not know the product but it looks like swap or the maxdsiz parameters of the kernel

Thanks Jeff,

I will look into those settings/readings when the error next occurs. Unfortunatly the user has had to reboot so they can carry on working !!
