Logical volume size growing

Server Model: HP Proliant DL 380 G4
Operating System: Red Hat Enterprise Linux AS release 3 (Taroon Update 6)

We have a server with the above said configurations. It has 2 logical volumes,
/dev/vg01/lvol1 /u01 - Space allocated : 15 G
/dev/vg02/lvol2 /u02 - Space allocated : 29 G

Oracle database (10g) is running in this server. 2 months back we stopped the OPMN running, since causing "http-web-access.log" log file to increase the size, at the same time we are not using any OPMN services. I nullified http-web-access.log file and during that time the size usage of /u01 was 51%.
After some days I found the size of /u01 was increasing slowly and now reached to 94%. I have tried to nullify the log files and deleting the audit (.aud) and trace (.trc) files, I couldnt manage to reduce the size. It is keep increasing. In fact for every few seconds some bytes are increasing. I execute the command "find . -mtime -1 -ls | more" to find the last 1 day modified/created files, nullify the log files, removed the trc and aud files. Still the size is not reducing as a major, it reduced to only a minimum when comparing to the increasing rate. I couldnt figure out the problem. Since it is production, I need to fix the issue before endup in deep trouble. Also I understand that it is not possible to extend the size of /u01 when it is live.

Any help to figure out the issue or reduce the space immediately would be really appreciatable.

Thanks in advance.

Could someone help me for my above post?
The growing size of the logical volume could be because of cache?
