> this is one of the longest running unbsolved problems we've ever had :-(
Not anymore. I've solved the issue this morning. Combination of two
independent problems:
Problem A:
- Poorly written PHP application (lucky me, not my fault...) -> tons of
PHP includes on every request
- Lack of noatime,nodiratime in /etc/fstab
- Use of ext3 with the default data mode (ordered)
I should be beaten for this. Still, it's a unknown issue why it worked
well without LVS.
Problem B:
A switch that mysteriously sends packets to the wrong servers. That was
not caused by the LVS-DR phenomenon you, Joe, have described in you
message last Wednesday, since I reconfigured for LVS-NAT again. We've
replaced the switch two times, now all packets arrive where they should.
I'll try to get back to LVS-DR tomorrow...
Thank you all for your help, guys :)
