skypopen is not marking messages as read   ?

i am facing a problum since august when i have upgraded  skype  to 4.3   after reading new skypopen how to  https://confluence.freeswitch.org/display/FREESWITCH/mod_skypopen  
i have 12 skype interfaces   with 3 skypenames (4 interfaces per skypename)
skypopen works fine    but after some days
 i noticed that some interfaces goes down
Don t know  WHY

when i start dead interface to see what happens  with this command

/bin/echo 'username  pass '| DISPLAY=:0  /usr/local/freeswitch/skypopen/skype-clients-symlinks-dir/skype101   --dbpath=/usr/local/freeswitch/skypopen/skype-clients-configuration-dir/skype101 --pipelogin &

skype login successfull  and i see contacts loading slowly and a lot of unread messages   and skype crashes again

then i removed
rm -rf  /usr/local/freeswitch/skypopen/skype-clients-configuration-dir/skype101/username

 cp -a /usr/src/freeswitch-1.4.6/src/mod/endpoints/mod_skypopen/configs/skype-client-configuration-dir-template/skypeclient01/skypenameA/*   /usr/local/freeswitch/skypopen/skype-clients-configuration-dir/skype101/username/

then it works fine  but after some days it happens again again

FreeSWITCH (Version 1.4.6  32bit)  skypopen with skype 4.3 on centos 6.5

has anyone faced this  or any solution to this  ?
