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

Hi,

that means the free RAM is not enough and krpano needs to use swap files - and the writing of the swap files fails due missing write permissions.

Try to set manually a folder where writing is allowed (by using the tempdir setting).

Best regards,
Klaus
