We have been getting a very occasional problem with third party application, where client process and Oracle shadow process seem to hang both waiting on read in Oracle network layer. Database is 11.2.0.4, and OS is AIX 6.1, although this has persisted through various versions of database (and application). Interesting that always seems to be within similar call-stack on application side (BatchReviseOnExit).
Leads me to suspect may be some kind of memory corruption on the client application side, but nothing I can identify from the source we have access to.
Have spend some time with support, but was just getting bounced between application side and database side (even though sides within Oracle, application is JDEdwards).
Wonder if anybody has any ideas about what I can do either pre-emptively to gather more information when it happens, or when application gets into this state.
I have pasted output from v$session and process stacks below. Patrick

select process, spid, state, status, event, paddr From v$session s, v$process p where p.addr = s.paddr and sid = 982
