RV Timeout while starting BusinessConnect Gateway server

I have configured an Internal server and the Gateway server on my servers and it was working fine. After a few days, the gateway server got stopped and I was not able to start it back. It was failing with the “Ack idle bootstrap failed: RV timeout after 300 seconds” error. Complete error trace is below.

I have fixed the issue by following the below steps. Hope this will help someone who facing the issue.

1. Checked whether the RV communication is working in both ways.
2. Ran the below queries in BC DB and truncated the tables

   select tname from tab where tname like "%_DUPLICATES".
   
   select tname from tab where tname like "%_INTERNAL".   
   
   select tname from tab where tname like "%_JOB" 
   

   The first query returned 6 table names as output. But none of the tables was having records in it. The second query returned 6 table names as output. Each table was holding 1 record and I truncated all the 6 tables (INTERIOR_S_95713532_INTERNAL, INTERIOR_S_87106214_INTERNAL, INTERIOR_S_59952039_INTERNAL, INTERIOR_S_51872776_INTERNAL, INTERIOR_S_46682888_INTERNAL and INTERIOR_S_26941778_INTERNAL).The last query also returned 6 table names as output. Out of 6 table, only one had 169 records and I truncated the table (INTERIOR_S_26941778_JOB).

3. If you have huge entries in BC_USER_PERM_ASSIGNMENT table then truncate this table. – Since we had only 460 entries in this table, I didn’t truncate this.
4. Add property “java.property.gs.dmzrv.timeout=300” in gsengine.tra and try restart the engine.

After restarting the BC and GS engine, I didn’t see any error in logs and I could see files are detected and processed with Response status in gs.log
