[Q] ADB pull file size limit !? topic

hey all, i have a nexus 5 hammerhead and am trying to pull mmcblock0p28 (data partition) using adb....it runs fine till after pulling 2.1Gb it stops giving "file too large" error (am on ubuntu) as for windows it doesnt even want to pull mmcblk0p28 as it is a directory not a file/folder.....i tried pulling the whole thing (mmcblk0) but still,stops at 2.1Gb
so is there some kind of size limit on adb pull command or what? and if there is how to overcome that to pull data partition?
PS: phone wont boot and all i can access is adb recovery(plz i dont want any how to fix the phone i just want how to complete the 13G pull)
check attatchments for screenshot..
thanks in advance :)
