#50517 Problem NDN cache count
Closed: wontfix a year ago by mreynolds. Opened a year ago by mreynolds.

Issue Description

I set up a generic instance of 1.4.1, with only a few sample entries in the database, but after doing a few operations the NDN cache count is very high (much higher than worker threads * number of entries). So either the count if off, or we are adding duplicate DN's to each thread's NDN cache.

Every thread has it's own NDN cache, so they may end up with duplicate numbers yes. As well the counter is asynchronously updated in the threads so I think this is not a bug - it's an 'estimate' not accurate.

Well I can't reproduce the large growth. But once I did see the count was at 2003 dn's in the cache, but there was only 19 entries in that db. So 24 worker threads * 19 entries is 456. So 2003 is a big difference. Was the counter off, or were we actually storing multiple DNs in the each thread's cache and wasting memory? Hard to say since I can't reproduce it.

I'm going to close this issue, and if I see it again I'll reopen it.

It's a count of the un-normalised inputs -> normalised forms, so 24 works * 19 entries * 4 different capitalisations of those (IE CN=Mark, cn=Mark, cn=mark, Cn=Mark, CN=mark). would quickly approach 2000 ish.
