Primary server communicates with the other for db replication on int0 interfaces.
But meanwhile we are using web interface running on int0 and sometimes it doesn't respond.
In order to investigate problem, I start ping to int0, int1 of the servers and saw that sometimes ping doesnt response on int0, but int1 on the same switch responding.
I changed switch in order to be sure about any problem on the switch, but ping problem appeared again.
The frequency of the problem: I cannot reach first box via ping for 10-15 seconds in every 10 minutes.
Is it possible that ping doesnt respond due to high volume communication on int0 of both servers?
or is it due to a problem on it? How can I check?
Could you help?
P.S I checked system log files and there were no hardware error there.
Thanks in advance
I would make sure you have at least a basic level of "Recommended Patches" on the box - these can often include kernel patches.
I would also swap out the UTP cables if you have spares - its a simple and cheap check that can often be missed.
Also is there likely to be any boxes that might have been allocated a duplicate IP address ? Ive seen in the past, because of the regularity of arp messages, two machines flip-flopping answering ping requests.
Ah yes...I seem to remember somewhere in my brain that Solaris does/did the odd thing of having the same hardware MAC address for multiple NIC's doesnt it ? Could that be confusing the switch ?
