I had remove kaddressbook from system, but problem still exists.

*** Bug 164323 has been marked as a duplicate of this bug. ***

Note:  you might look at bug 162013 (and the last comment from the bug reporter)

Hej,

well, what shall I say... you vCard is too big :)
The linux system runs out of memory in your case. Please try to
split up the vCard in several smaller ones and then use the
directory based address book as backend.

Ciao,
Tobias

The development of the old KAddressBook will be discontinued for KDE 4.4.
Since the new application has the same name, but a completly new code base we close all bug reports against the old version and ask the submitters to resend there reports against the new product.
