Could you please attach console output with oops/panic data? Also, what file system type is supporting the target directory? Ernie , How do I get the console output with oops/panic data? The machine is frozen and has to be hard rebooted by swith power off and on. Please advise. Thanks. Created attachment 101658 [details]

What's the status of this bug? I have a Dell 2650 with 3 GB RAM running RHAS3 kernel 2.4.21-20. When I copy using cp a ~ 1 GB file from one directory to another on the same disk, memory use goes up by about 1 GB and stays up even after the operation is done. I understand that the memory is used by a disk cache for later improved copy performance. But the memory never seems to get released and another large copy will use up all the memory, often causing a system hang (frozen screen). Does cp really have a memory leak for large files? I tried the following test: dd if=/dev/zero of=/tmp/testfile bs=1M count=1024 ; rm /tmp/testfile which I got from Bug 58681, and the memory used by this operation was freed up, but the memory used by the previous 1 GB cp is still shown as used. Tony, please work with Customer Support to get the required data (and then attach it here). Also, please let us know if this problem occurs with a recent RHEL3 release (U5 or later). Thanks in advance. Reassigning to PeterS. |
