ABAP cache is not updating in ID

Hi Experts,

We are SAP PI 7.0 SP16 When we try to create or change the existing objects in ID, the objects are activating but when we check cache notifications in ID the status is in Error. The date and time is showing as "00.00.00".

--> We have checked the SXI_CACHE it is up to date.

--> SLDCHECK is working fine.

--> Delta and Full cache refresh.

--> RFC destination INTEGRATION_DIRECTORY_HMI is giving "500 interval server error"

--> Adapter engine URL is maintained in SXI_CACHE [We also tried and loaded the URL automatically]

--> When try repeat cache update for instance it is giving the below error as shown in the below screenshot.

. 

When we perform delta cache refresh in SXI_CACHE, ABAP cache [ID] is updating and it is showing the correct date and time,but still perform notification is in Error status.

Please share your suggestions to fix this issue.

Thanks in advance.

Regards
