I am trying to run a linux high availability cluster (failover pair)
using serial as one of the heartbeats.
Due to numerous serial over-runs the systems are actually crashing
periodically.
This is a very frustrating development for a system intended to provide
HA. (certainly not ha ha ha).
I have updated to the latest bios.
I have checked RTS DTS XON XOFF etc.
This is happening with the stock and custom kernels.
This is happening on three pairs of servers.
The serial ports are detected as:
Serial: 8250/16550 driver $Revision: 1.90 $ 32 ports, IRQ
sharing enabled
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
Any advice would be greatly appreciated.
Thank you.
