Error in opening datafile after use of DATAFILE RESIZE command

Question

Hi Friends,
I am facing a strange problem here. We got a space problem yesterday ORA-01659: unable to allocate MINEXTENTS beyond 42 in tablespace and I increased the underlying datafiles using resize command. The datafiles were 1G earlier and I have increased them to 2G using the command
ALTER DATABASE DATAFILE 4 resize 2G;
It went fine and I saw the free space in my tablespace. But after this when I try to drop a table using a script which connects to this db as a schema owner ( the script just selects all tables from dictionary and drops it using 'drop table x cascade constraints' , It thorws the following error
ERROR at line 1:
ORA-01116: error in opening database file 4
ORA-01110: data file 4: '/SAN/p0/oradb/CBA11/data/avient01CBA11.dbf'
ORA-27092: size of file exceeds file size limit of the process

On going through metalink, I found that there could be problems with ulimit parameter in the OS. My OS is SunOS 5.8 Generic_117350-28 sun4u sparc SUNW,Sun-Fire-480R and my oracle version is 10.2.0.1.0 . I have set the ulimit parameters for file size to unlimited for both hard limit and soft limit.

These solutions are suggested as per MOS note ID 271331.1. However the issue is still persisting. I am not getting any clue on whats happening. Any help is appreciated.
Thanks

Thanks for your hint.
yes, I did and the following is something more strange. I can't figure out !!
The ulimit is only different for stack for hard and soft. file size is still unlimited. The same drop table doesn't allow me when I connect as schema owner directly !
