Error 12335



Message text

An attempt was made to read logical page '%d' for object '%d' in database '%d'. The page was not read successfully because of repeated failures to acquire the page using asynchronous prefetch.Explanation


A problem occurred when another process tried to read the indicated page asynchronously. Adaptive Server checks whether the retry threshold (10 times) for the page has been exceeded and raises error 12335 if it has.


It is possible that this condition is due to an Adaptive Server resource shortage. Ensure that the configuration parameters max async i/os per server, max async i/os per engine, and disk i/o structures are set high enough for the volume of I/O is being done.

Additional information

In Adaptive Server 15.0 and later, error 12334 is raised instead of 12335. See “Error 12334”. If the 12335 error persists, it may be necessary to gather a configurable shared memory dump (CSMD). See “Obtaining a CSMD” in the Troubleshooting and Disaster Recovery guide section Other Useful Tasks.”
