appying dos2unix on all files under folder

I am trying to appply dos2unix on all files.

find $WORKSPACE/itrp-sr -type f -exec unix2dos.exe {} \;

but is resulting in an error

1 [main] find 3468 fork: child -1 - forked process 4524 died unexpectedly, retry 0, exit code 0xC0000142, errno 11 find: cannot fork: Resource temporarily unavailable

This may be due to insufficient memory?
