OMS OXML broken output, slow work

#1
Hello!
I have SPSS 22 x64, and SAV file with about 400 cases. Syntax is
Code:
FREQUENCIES VARIABLES=var01 var02
  /ORDER=ANALYSIS.

OMS
/SELECT ALL
/DESTINATION FORMAT=OXML OUTFILE="xmlout.xml".
XML file appears with 0 size, than, after some time, it becomes bigger, but unfinished. For example, after about 40 minutes it ends by the near last but one element of var01 frequencies table

HTML:
"<category number="23" text="23" varName="var01"><dimension axis="column" text="Statistics"><category text="Frequency"><cell number="7" text="7"/></category><category text="Percent"><cell decimals="1" number="1.7073170731707" text="1,7"/></category><category text="Valid Percent"><cell decimals="1" number="1.7073170731707" text="1,7"/></category><category text="Cumulative Percent"><cell decimals="1" number="99.512195121951" text="99,5"/></category></dimension></category><category number="24" text="24" varName="var01"><dimension axis="column" text="Statistics"><category text="Frequency"><cell number="
Also, in Python 2.7
Code:
spss.Submit("""FREQUENCIES VARIABLES var01 var02  /ORDER=ANALYSIS.
    OMS /SELECT TABLES /DESTINATION FORMAT=OXML OUTFILE='xmlout.xml'.
    """)
creates file with only word "</outputTree>".
