Re: Dbus is getting hung at some point

We have two applications, AHNC and nethealthd, that interacts with CCSP
library and thereby with dbus, to frequently update certain parameters via
periodic call backs. Apart from experiencing bus_timeout for such parameter
updates (This happens at some random instance, usually post ~2+ hrs of long
run), these applications are doing the rest of the activities that they are
intended to do.

GPV wraper APIs from applications -> CcspBaseIf_getParameterValues ->
CCSP_Message_Bus_Send_Msg ,
where in, at some random instance (~post 2 hrs of long run, either
AHNC/nethealthd experiences CCSP_BUS_TIMEOUT post the timeout reached.
check here
<https://code.rdkcentral.com/r/plugins/gitiles/rdkb/components/opensource/ccsp/CcspCommonLibrary/+/c0a0632e0cb179b66918e73b35f9765368dd5b80/source/util_api/ccsp_msg_bus/ccsp_message_bus.c#1735>

This isn't a problem with CCSP, as the calls exit properly, and other
applications that uses CCSP library calls are still functional.

PS: AHNC (CCSP.ahnc component), nethealthd (is a private application that
does periodic gpv request for both CCSP.ahnc and few other CCSP component)
If the dbus call from AHNC is hung at some point, then nethealthd faces
bus_timeout for gpv request of params that are registered in ccsp.ahnc,
while the dbus response for other CCSP components at the same time is still
responsive.


Then after around 30mins or less, all the gpv requests/ dbus calls fails
and every component becomes unresponsive.
