Hi all,


I am seeing some unexpected unloading behaviour of CMPI based C providers
in SFCB. It is expected that if any provider has subscriptions lying in the
interop/implementation namspace OR on MI cleanup routeins
"CMPI_RC_NEVER_UNLOAD" being returned to the cimom, then the provider won't
unload. But after doing all these my provider is still getting unloaded
after some unspecific (random) amount of time/calls. I have even extended
the unload time property in /etc/sfcb/sfcb.cfg to 12000, which I think is
more than enough.


To confirm whether the provider is unloaded due to a seg fault, I had set
"ulimit -c unlimited" in /etc/init.d/sfcbd script, but did not get any
zdump core files. To further convince myself, I wrote a very basic CMPI
based C provider, with only the interfaces returning success. This provider
had no chance of getting a seg fault ever, but still it won't remain
loaded :(.


My query is that, is there any known issues regaring C providers in sfcb
related to this unloading pattern? Am I missing anything which could
possibly prevent my provider from unloading?


Thanks in advance,
Biswaparatap.
