After the upgrade to Version 9.5.5 my clients are stuck on the date of upgrade on the console. i.e last report time on console shows 18th April which is the date I upgraded the server. However a few clients about 10 out of 6000 are updating the current last report time. On troubleshooting I’ve noted that the clients reporting fine have an old version of ActionSite.afxm while all the other clients have a latest ActionSite.afxm including the server which shows its last report time on console as 18th April. From the database on the Computer table I see ‘lastreporttime’ is today for like 98% of the clients while the ‘lastreportsent’ is 18th April. Kindly can some help me out? Also all the automatic computer groups on the console arent updating anymore 
From the FillDB.log I see this error repeating since 18th April:
Unable to parse chunk of compressed file in buffer; discarding chunk. (Client certificate revoked. Discarding message from computer 1520482)
From the BESRelay.log I have:
DatabasePropagator (6176) - Error processing file Relays.dat:Database Error: A database query unexpectedly failed to return any results.
The BESClient.log has no error and shows ‘Report posted successfully’ for each action.
