Guess what? this is what I was able to find through a simple google search. I hope this would help you to fix the problem
This problem is two fold.
1. PMON reports bogus error message on LINUX:
'OER 536879337 in Load Indicator : Error Code = 562331928 !'
see Solution #1 and BUG:987647
2. Messages 'Load Indicator not supported by OS !' filled up the
see Solution #2 for workarounds
Apply patch for Metalink ->[BUG:987647].
This bug is port specific for LINUX.
Note that this patch only fixes the problem with inccorect PMON messages.
It does not eliminate the 'Load Indicator not supported by OS !' messages.
There are a couple of workarounds for eliminating these
messages -- 'Load Indicator not supported by OS !':
1. Run crontab on alert.log to save good error and drop Load Indicator errors:
eg. cat alert.log | grep -v "Load Indicator ...." > alert.good
2. Disable MTS may eliminate these messages.
There have been a number of bugs reported on this issue.
Currently, these bugs are still under investigation and no patch
is available at this time.
Disable MTS may work as this is related to Metalink ->[BUG:723579]. This bug is
fixed in 8.1.4 but this fix does not appear to be included in
8.1.5. Please see Metalink ->[BUG:1109425] and Metalink ->[BUG:1103673].
There have been a number of bugs reported on this problem and these
bugs can be divided into 2 catagories.
1. This is not a bug. The message indicates that the kernel load statictics
is not supported.
see Metalink ->[BUG:984456] and Metalink ->[BUG:1164889]
2. The cumulation of 'Load Indicator not supported by OS !' messages
could casue PMON to return ora-000601 and crash.
Metalink ->[BUG:1109425] PMON crashed with ora-601 on LINUX
The last reply is pretty complete and explains the issue in detail. Ijust upgraded to 188.8.131.52.0 on Linux and I am still seeing the error. Basically, this issue is specific to Linux and the reason being Oracle does not support the kernel load statistics. It is more of a nuisance seeing the error pop up, the error is bogus. You can disregard it.
