This is a leak summary from a run of crlutil on Win2K under purify. If I delete
nssckbi.dll, there is no leak.

Looks like NSS_Shutdown creates mutexes that don't get cleaned up!

Here is some more recent leak data from NSS 3.11.2 provided by Anton . His program mostly did NSS_Initialize / NSS_Shutdown in a loop . But it appears C_FindObjects is used and leaks, so that would be a serious problem for anyone using the module.

We need to perform more testing in an actual application (ie. selfserv/strsclnt) to get a better list of leaks in this module, but this is a good start .

All those stacks with the word "once" in the names of their functions
only occur once, right?  
Oddly, I only see PR_CallOnce in SOME of those stacks.  :(

Nelson,

These latest stacks occur once per NSS initialization . They can happen more than once during the execution of a given program. Some programs initialize and shutdown NSS multiple times - eg. a browser doing profile switching, an LDAP library being opened and shutdown multiple times.

I played around with the root cert module, strsclnt and selfserv. So far, I haven't been able to find any leaks other than these one-time problems. But my tests were pretty basic, with my own cert and public SSL servers. We probably need more public certs that chain to the roots to do proper testing. At least the good news is that builtinsC_FindObjects doesn't repeatedly leak - that would have made the module unusable in servers . We would probably have heard more complaints by now . That's the good news. The bad news of course is that there are 6 init-time leaks to fix.

After adding root certs module to test suite this leak occurs also there (on Solaris platform).

Slavo, All the leaks reported in comment 7 are "tracker" leaks, 
leaks that occur only in debug builds, and that are leaked by 
the code in tracker.c, because tracker's finalize function is 
never called.

tracker leaks are now recorded in bug 397476.  

if the ONLY leaks remaining in nssckbi are the "tracker" leaks
then this bug can be marked as a duplicate of 397476.

Bug 397476 was resolved as a duplicate of bug 370536.

According to the "ignored" file, all the stacks associated with this bug
number are tracker stacks, and the patch for bug 370536 will (if reviewed
and accepted) eliminate them all, so if there are no other CKFW leak 
stacks, then it seems this bug has become a duplicate of bug 370536.

But if there are other CKFW leak stacks in ignored, the entries in that
file should cite this bug.

Bug 397476 which list the original leaks is now fixed. The additional leaks are definately in bug 370536 so resolving as dup.
