Hi its me again
Looks like ive found what problem was. Earlier ive been using io with php_psio. Php_psio generates different .ioFTPD files than ioSFV. So in every folder i had psio .ioftpd files. Then ive installed iosfv, and from that time crashes has begun. You cant have 2 types of .ioftpd files in different folders ofcourse coz io will crash.
