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
