Show a file given by me with command cat, xshell sometimes give some strange behavior , looks like buffer overflow(data receive buffer recovered input data buffer)

2、redhat AS4 (Red Hat Enterprise Linux AS release 4 (Nahant))
Show the file ( with cat )given by me will directely make xshell die (take 100% cpu with no response).


3、The given file is a text log file ,becouse it is too big(9.3M compressed with gzip), if you want it, I will mail you.

We are currently working on this problem. Please check back soon for an update.

Thank you.

The problem on AIX 5.3 is still there.
The attachment is one of the log showed on Xshell.
But the file make the probelm is too big to put here.
The problem is use cat to show a big log file, some times buffer will overflow and maybe the receive buffer will cover the send buffer and something(I don't know if it is a bug of bash downed from ibm's web site or xshell).

We have tested Xshell 3.0 Beta (Build 0164, released on Sep 12, 2007) with big size log files (over 10M), but failed to duplicate this problem.

Please send the problem log file to support@netsarang.com.

Thank you for your cooperation.
