iApp for LDAP issue

HI,

TMOS: 11.6.0 + HF6 I have an issue with iApps. I have two applications deployed with f5.ldap. When checking the standby LB the iapps are not longer visible in the GUI. When checking for the configuration in the bigip.conf files it only exist in the .bak files on both active and standby.

I'm getting the following error in the LTM log:

Sep  9 11:26:31 slot1/bigip1 err mcpd[8507]: 01070712:3: Caught configuration exception (0), Internal error, can't load folder or nested folder for: /Office/VS_ldap.app/VS_ldap_vs /Office/VS_ldap.app/VS_ldap_lan_optimized_tcp.

When checking for the folder with tmsh list sys folder, the VS_ldap.app does not exist.

I tried to run an update on the Reconfigure tab on the Application server deployment, byt then I get the following error:

Error parsing template:can't eval proc: "script::run" iapp::get_items ltm persistence source-addr: can't get object count from mcpd while executing "error "$error_msg $err"" invoked from within "subst $rval($do_binary,$tmsh_rval,$nocomplain)" (procedure "iapp::get_items" line 76) invoked from within "iapp::get_items ltm persistence source-addr" (procedure "script::run" line 3) invoked from within "script::run" line:1

I have check the validity of the configuration by running tmsh load sys config verify, no issues found there.

Best Regards Andréas
