We were using the xdelta version 3.0.0 and recently moved to V3.0.11 and we see that the xdelta3 takes lot of memory and the demon gets killed or the whole system reboots.
We are using the command as below generate the differential image on the PC
xdelta3-pc -e -f -s sys_v1.ubifs sys_v2.ubifs sys.diff
And the below command is run on the ARM cortex 7 target to regenerate the full image sys_v2 using the sys_v1 & the delta sys.diff
xdelta3 -f -d -s sys_v1.ubifs sys.diff sys_v2
The memory issue can be seen as below
Out of memory: Kill process 1105 (xdelta3) score 302 or sacrifice child
Killed process 1105 (xdelta3) total-vm:78844kB, anon-rss:51100kB, file-rss:88kB
This is a sporadic issue and is happening for few of the images.
We tried to use the option as below
xdelta3 -I 2 -f -d -s sys_v1.ubifs sys.diff sys_v2
and it seems to be working but not sure if its a proper way of doing it.
Can you please explain more on the memory options and how does this work, what is the best command to use here?

memory options: -B bytes source window size -W bytes input window size -P size compression duplicates window -I size instruction buffer size (0 = unlimited)
Any suggestions?
