example: network ip 192.168.0.9/24 but it sends arp for 192.168.68.1 etc.

after restart all is working properly some time and then again
can you please suggest me solution?

is that SLES11SP2 machine at the latest patch level?

Unless you have some according support contract, you'll have difficulties getting support for your OS level: SLES11SP2 is end-of-life since Feb 2014.

If you cannot update to SP3 and already have installed the latest patches (published Jan 2014), we might find some cause and/or fix (or work-around) via further discussion.

Regards,
Jens
