Hi Ritesh,
You're absolutely right -- if it's a configuration issue, it is not
likely to work at all.
If the whole machine is hanging, it's probably not a problem with
piranha itself - it's likely a kernel issue (my guess would be in the
ipvs code). Personally, I haven't seen this problem before.
I would call Red Hat support at this point. Chances are good that Red
Hat Support will want at least the following:
(a) kernel version
(b) piranha version
(c) Task stack traces (sysrq-t, or BRK-t over a serial terminal)
(d) kernel PC (sysrq-p, or BRK-p over a serial terminal)
(e) memory info (sysrq-m, or BRK-m over a serial terminal)
(f) Full sysreport
