I have an application which is doing a lot of file operations.Its doing a lots of file read and write operations(lot of small files). We have found that some of the files are getting mixed up randomly. Output of file1 is going to file2 and so on. There is no concurrency issue from code that we have verified. Its working in all other platforms expect AIX.
In Solaris we faced this issue, but after enabling directio this issue is resolved.
In AIX we tried to enable dio, still this problem persists.
- OS : AIX 18.104.22.168
- Architecture : Power 6;
- 8 core with SMT on
- Storage : SAN
- FileSystem : JFS2
