Kathy,
I just finished testing. This "fix" fixed my problem. My cache_load is
finally invoked. Maybe MFD is more memory intensive but if you don't mind
the extra memory, this would be a way to get un-stuck in your present
situation.
cache->flags |=
(NETSNMP_CACHE_DONT_AUTO_RELEASE | NETSNMP_CACHE_DONT_FREE_EXPIRED
| NETSNMP_CACHE_DONT_FREE_BEFORE_LOAD | NETSNMP_CACHE_PRELOAD |
NETSNMP_CACHE_AUTO_RELOAD | NETSNMP_CACHE_DONT_INVALIDATE_ON_SET);
