Joseph MacFarlane commented on ISPN-1680:
-----------------------------------------

We're currently using 4.2.1 (and production instances will continue to do so for the foreseeable future). We found that retrofitting this fix resolved 'Read past EOF' errors arising from high volumes of simultaneous search and update with the following stack trace:
