Suximage opens a pipe using popen to ximage. It strips the headers and sends the
headersless data down the pipes. Evidently it allocated memory. Perhaps suximage can
be rewritten using memory mapping (mmap) instead of malloc, but perhaps it will work for
you if you kill all other memory hogs. Maybe best to reboot and run it before other
processes allocate memory.

Dear all,
I am trying to open a 12Gb byte sgy/su file using seismic unix, and I get the below error
message.
/home/subbarao/SU43R3/bin/ximage: ealloc.c: malloc failed (Cannot allocate memory)
Is there a file size limitation in SU? or is the error related to display or something?
Do I need to change any settings?
Thank you and look forward to your early response.
Cheers,
Subbarao.
