IMHO, you should add more swap space.

Hi Lee,

I think the problem must be Insufficient Kernel Resource.You receive "Out of memory" exception from mxexec..

Plz Verify the kernel parameters against those listed in the system requirements at:

Probable Fix might be :
Increase associated kernel tunables including threads and stack & SWAP space required.

I posted to bugzilla for ask this case, they told me add more swap files to system. I will try that for add more 2GB swapfile.

#dd if=/dev/zero of=/swapfile bs=1024 count=2097152
#mkswap /swapfile
#swapon /swapfile

Hi

The swap seems to be the issue here, looks like u added 1GB swap which should be good, you can check the swap usage with free.

Thx
