Segfault in our DEV environment

0 Kudos

Hello,

In our DEV environment, we are experiencing daily slowdowns where the system crawls for about 5 min, then everything

seems to go back to normal.

I cannot determine the root cause of this, however, in our Unix (message) logs, I have found that the following

segfault hits us every time this occurs:

<servername> kernel: [4645603.113988] gdb[28298]: segfault at 1 ip 00000000006b3560 sp 00007fff239efa28 error 4 in gdb[400000+51d000]

Our system is running SAP  (ECC SAP ECC 6.0 NW7.0, BI NW7.0, and PI SAP NetWeaver 7.3) 3 instancnes on Oracle 11.2.0.2.0.

on:

SUSE Linux Enterprise Server 11 (x86_64)

VERSION = 11

PATCHLEVEL = 3

Is there a way I can find out what is causing this?  when this hits us, all SAP systems slowdown, and are unusable / unreachable.  We also

have an incredibly hard time moving around the OS (i.e. LS takes forever to come back).

Any help is greatly appreciated

Thank you

Richard

Hi Richard,

Sometime hardware or faulty memory or driver can also create this problem .Share the results for command ulimit and what are the permissions on /etc/rc.d/init.d .

Thanks,

Gaurav

Check if core file was generated as result of this error.

Hi Richard,

On searching for your issue i found below docs for your ref.Request you to please navigate with these and i also suggest you to try with RAM replacement for the server.

SEGFault on Kernel(?) ext4(?) or something like that

Hi and thank you Gaurav,

I will send the info about RAM to our Unix team...  as for the output you asked for:

we do not seem to have an init.d in the path you specified.

xx2:/etc/rc.d # ll i*

-rwxr-xr-x 1 root root 14041 May 24  2013 ipmi

-rwxr-xr-x 1 root root  2290 May 11  2013 ipmievd

-rwxr-xr-x 1 root root  3002 May 11  2013 irq_balancer

-rwxr-xr-x 1 root root  4275 Nov  8  2010 ivman

xx2:/etc/rc.d #

and for ulimit

xx2:/etc/rc.d # ulimit

unlimited

xx2:/etc/rc.d #

Thank you again!
