I forgot to say that the "table flag" I mention below is a local variable
meaning the table was changed since I last reloaded (possibly by CLI or
whatever). This is similar to the example mentioned of checking a change
date on a file before reloading the table data from the file. FYI.

Re: Cache load does not get called
I tested with various flags. Here is my code:
/***********test code *****/
// use these 3 for check table flag before freeing and reloading
cache->flags |= NETSNMP_CACHE_DONT_FREE_EXPIRED;
cache->flags |= NETSNMP_CACHE_DONT_AUTO_RELEASE;
cache->flags |= NETSNMP_CACHE_DONT_FREE_BEFORE_LOAD;
// use this one for set commands
cache->flags |= NETSNMP_CACHE_DONT_INVALIDATE_ON_SET;
// testing this one - periodic auto-refresh
// cache->flags |= NETSNMP_CACHE_AUTO_RELOAD;
/* end test code ********/
I did not use the MFD mib2c because it was posted in another thread that it
is a poor performer so our code may be different. I used
mib2c.table_data.conf. FYI.

Re: Cache load does not get called
In my case reload flags were not set. NETSNMP CACHE RELOAD. See if
that helps. It should be set at the bottom of the function
container_init. See example in if-mib. I'm trying it out now.
