[Freeipa-users] FreeIPA (directory service) Crash several times a day

[dev at mdfive.dz]

Hi,

The Directory Services crashes several times a day. It's installed on 
CentOS 7 VM :

Installed Packages
Name        : ipa-server
Arch        : x86_64
Version     : 4.2.0

# ipactl status
Directory Service: STOPPED
krb5kdc Service: RUNNING
kadmin Service: RUNNING
ipa_memcached Service: RUNNING
httpd Service: RUNNING
pki-tomcatd Service: RUNNING
ipa-otpd Service: RUNNING
ipa: INFO: The ipactl command was successful


Before each crash, I have these messages in 
/var/log/dirsrv/slapd-XXXXX/errors :

     [30/Jun/2016:09:35:19 +0100] ipapwd_encrypt_encode_key - [file 
encoding.c, line 171]: generating kerberos keys failed [Invalid 
argument]
     [30/Jun/2016:09:35:19 +0100] ipapwd_gen_hashes - [file encoding.c, 
line 225]: key encryption/encoding failed


Any help?
Best regards
