My AIX 4.3.3 box crash when swapping to disk.

[Madz]

The system does not write any logs or print to serial device.

The swapping are are being used for some seconds and then the system hangs.

How to prevent from hanging?

Thanks in advance

Are then any errors in the error log ?
does the LED show any codes on reset ?
Is this part of an HACMP cluster ?
How much memory do you have ? ( lsattr -E -l mem0 )
how much paging space ? ( lsps -a )

 

[Madz]

No error log is written or directed to serial port.
The system just freeze and the led shows nothing.
I have 256 Mb RAM and the page is 1280Mb.


I cannot figure out why the system hangs when the load increases?

Thanks you your support.

When it hangs can you ping the box but not get a telenet login ?
Are you using TSM for backups / archives ?

I would:

1.Run extensive diag on all HW - proc,memory,cash,boards ,etc

2.perform error log analizing using via diag :

Run: diag -> Diagnostics routines -> Problem determination

This selection tests the system and analyzes the error log if one is available.

The output may be:
A PROBLEM WAS DETECTED ON Tue Jun 19 12:59:09 WET 2001 801014
The Service Request Number(s)/Probable Cause(s)
(causes are listed in descending order of probability):

A03-150: I/O Expansion Bus Connection Failure.
Error log information:
Sequence number: 30
n/a FRU: n/a P2
n/a FRU: n/a 1
n/a FRU: n/a P1
n/a FRU: n/a P1
------------------------------------------------------------In this case it would normally mean a HW motherboard problem. Lev
