Re: [CentOS] Cluster Heart Beat Using Cross Over Cable

Since it is a very critical and busy server may be due to heavy network load some hear beat signal is getting missed resulting in shifting of service from one node to another.

For automated takeover systems, especially critical ones (tho you can argue that any system setup with automatic takeover is critical by definition), you should have multiple heartbeat paths. Ethernet, serial cable, on shared disk, fibre or whatnot.

Having false takeovers due to missed heartbeat on one set of ethernet cards could also likely be missed on another set of cards, even with a crossover cable.

Maybe you should investigate alternate paths?
