Hello bitmaps are allocated in samba with bitmap_allocate. The function bitmap_free is NEVER called. There are other functions in samba that are never used lib/charcnv.c acnv_u2ux lib/util_str.c smb_ucs2_t *all_string_sub_wa libsmb/asn1.c asn1_read_Integer(ASN1_DATA *data, int *i) What about to delete them ? Bye Andreas
