Swap file creation error

Hi Guys,

I am trying to use krpanotools to create virtual tour using php script but sometime (not always) it throws below kind of error and fails.

creating file kvmem_1620_00000046.swap failed: Permission denied (errno=13)

Is it some RAM problem ?
As I read on some other thread that it should be because of not having enough disk space (temp folder) for creating temporary files. But I think /tmp folder has decent disk space on my machine.

OS: Ubuntu
RAM : 1GB
DISK size: 8GB
File sizes are almost 2 MB (max 3-4 files)

It fails sometime with above error and after sometime it starts working again without any manual changes. First I suspected it to be RAM problem but even it failed with one process only.

Any suggestions are welcome.

Thanks,
Amit Suthar
