User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

Description of problem:
After about 4 days since reboot Oracle TNS-listener process hangs on attempt 
to open new Oracle-session

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
It is really hard to explain
1. Install Oracle 9i Database Release 2 under RedHat AS 2.1 on Dell PowerEdge 
4600 (6Gb RAM in 'spare bank' mode)
2. Linux Kernel parameters: bigpages=2048M profile=2 nmi_watchdog=1
3. Relink Oracle products to utilize asynch IO, and set /proc/sys/kernel/shm-
use-bigpages to 2

Actual Results:  After about 4 days of business activity Oracle TNS-listener 
stops to respond via 'tnsping abc', 'lsnrctl stat', ...

Expected Results:  TNS listener should be available 24*7*365

Comment 4 Boris Mironov 2003-03-15 17:08:15 UTC
Good news!

Kernel enterprise-2.4.9-e.14amazon seems to be free of the bug.
Currently, Oracle TNS-listener works for more than 7 days without hung.
