We had a server unexpected halt and after that we cant start zimbra by running zimbra start.

the startup.log says

Host mail.compay.com
Starting ldap...Done.
Failed to start slapd. Attempting debug start to determine error.
TLS: error:0906D06C:PEM routines:PEM_read_bio:no start line pem_lib.c:650
TLS: error:02001002:system library:fopen:No such file or directory bss_file.c:356
TLS: error:20074002:BIO routines:FILE_CTRL:system lib bss_file.c:358
main: TLS init def ctx failed: -1

we found a work around starting ldap manually with

sudo /opt/zimbra/openldap/libexec/slapd -l LOCAL0 -4 -u zimbra -h ldap://mail.company.com:389/ -f /opt/zimbra/conf/slapd.conf

and then

sudo zimbra
zmstorectl start
zmnginx start
zmspellctl start

Any idea how to fix this problem? seens like a certificate problem but we already have reinstalled the commercial certificate but the problem persist.
