[Samba] vfs_fruit kernel panic 10.9.5 when saving from adobe illustrator cc

[Sascha Kasch]

dear list,

thanks for the great fruit speed-improvements. but...

server config:
debian 8 jessie
sernet samba 4.2.2 packages

here we see a problem that might not only be fruits problem but
results in macosx 10.9.5 crashing with a kernel panic when saving from 
adobe illustrator cc or cc 2014:
(does not happen when saving from photoshop cc or cc2014)

       Kernel Extensions in backtrace:
com.apple.filesystems.smbfs(2.0.3)[EC68D5F4-45EA-379A-B723-AEEDE9C94055]@0xffffff7fac647000->0xffffff7fac692fff
             dependency: 
com.apple.kec.corecrypto(1.0)[DB137B94-65D2-32AF-B5BC-80A360E104C3]@0xffffff7fab362000
             dependency: 
com.apple.kext.triggers(1.0)[A7018A2E-1C0C-37B8-9382-67786A396EAF]@0xffffff7fabd1d000 


does occur on third or fourth save.

happens with smb.conf like this:

[global]
    workgroup = domain.com
    server string = %h server
    log level = 2
    os level = 60
    security = user
    case sensitive = no

    printcap name = cups
    max protocol = SMB3
    use sendfile = true
    vfs object = catia fruit streams_xattr acl_xattr
    fruit:encoding = native

    ldap ssl = off

    ldap admin dn = "cn=admin,dc=domain,dc=com"
    passdb backend = ldapsam:"ldap://is.domain.com ldap://it.domain.com"
    ldap machine suffix = ou=systems
    ldap suffix = dc=domain,dc=com
    ldap timeout = 30

    idmap config * : backend = tdb
    idmap config * : range = 1000000-1999999

    idmap config domain : backend = ldap
    idmap config domain : range = 3000000-3999999
    idmap config domain : read only = yes
    idmap config domain : ldap_url = ldap://is.domain.com/
    idmap config domain : ldap_base_dn = ou=idmaps,dc=domain,dc=com
    idmap config domain : ldap_user_dn = cn=admin,dc=domain,dc=com

     map archive = No
