Hi Sir Alvin,\n\nAs per Actian the SIGSEGV error on ActianSvr, seems to be different from the production error which was patched on 15854.\n\nIt could have happened due to ungraceful shutdown of the server during patch installation.\n\nI have attached a KB on this case, though it covers only a portion of the error message which appeared in the errorlog, but it looks relevant.\n\nPlease take a look and apply the resolution on KB.\n\nAlso, there's a lot of logical locks recorded on errorlog. Please consider updating the per_tx_limit.\n\nThank you.\n\nManilyn
