Yes, there was such a hint; the SIGXFSZ error is thrown when that error message 
is reported:

"Alert log :
ORA-07445: exception encountered: core dump[pwrite64()+19]
[SIGXFSZ] [ADDR:0x1F6000004D6] [PC:0x322B40E613] [unknown code] []
ORA-07445: exception encountered: core dump[pwrite64()+19]
[SIGXFSZ] [ADDR:0x1F6000004D6] [PC:0x322B40E613] [unknown code] []"

I have seen this before when the filesystem is configured for a 2 GB file size 
maximum; I reported it here:


Cut 'em off at the pass! Or, why is my piped export file truncated?

Sometimes you need to conserve space on a file system, and using exp with a 
named pipe to the compress utility is a nice way to export large databases and 
consume t...  
View on dfitzjarrell.wordpres... Preview by Yahoo  
  as a cause for piped export file truncation when using the older exp utility.

Hello sir,
I would like to understand how you figured it out that the above errors were 
due to "max file size exceeded". 
I mean no such hint was there in error logs but u catch the problem so 
precisely.
Any clues how you figured it out.
Thanks n Regards,
