LTM1500 v9.1.3
Hello Again,
OK, I have an LTM 1500 with version 9.1.3 (I know!) of the code. It has been fine for years. Recently added a new virtual server, with necessary pool, pool members, ports, health monitors etc.
What happens is that the virtual server will listen on port 80 for a time and then just stop. On the load balancer I can see the VS, the pools and the nodes as up. I can telnet to the VS on port 80 from the LB itself and I can telnet to each pool member on the necessary port from the LB, but not from a workstation with a browser.
Networking is fine, firewalls are good.
The only way I can get the thing back is to delete the VS and re-create it and it starts working again for a time.
The unit has some 100 virtual servers running various apps and these appear fine, it just seems to be this new one.
I may re-create all of it (someone else created it but looks fine to me), vs, pools, members.
The units have been up for 638 days our support say there is a bug in 2.4 linux kernel where over 497 days it can start behaving oddly and recommend a reboot. It is just weird that older vs's work fine it is just new ones that have this issue.
Anyone seen this before ?
Thanks,
George
- boomchke_11156NimbostratusHave you performed a reboot to see if that clears the issue? I would certainly start there. If it doesnt, then you could start looking at the possibility of only the new VIPs causing problems. I cant say that I've ever seen that before. Do you have a standby or lab box you could dump that new VIP config on to see if it causes the same issues? When it stops listening have you done a TCPDump or packet capture to see if the traffic is hitting the F5?
- George_32239NimbostratusHi, thanks. I think first I am going to delete the pool and then the VS and re-create it and see what happens. Then I will try a reboot. I will post back what happens. Weird though never seen that before
- Anthony_GraberEmployeeRegardless, I would recommend a reboot. It's a linux kernel issue...you will see problems.
- hooleylistCirrostratusUpgrade! Even if you don't have an active support contact now, you can upgrade to a version that was released when the unit(s) last had support:
