After payment (withdrawal) ~ 1000 CROC, wallet freeze for ~5 minutes.
In debug.log I can see a lot of lines like this:

I don't know what process is this, and how to get rid of freezing?

At the source on Github I searched for WalletUpdateSpent and it returned two results (as shown here): https://github.com/RangaBoom/CrocodileCash/search?utf8=%E2%9C%93&q=WalletUpdateSpent&type=

It seems to be calling the function at line 345 of wallet.cpp (the other result is in the associated header file on line 179 of wallet.h). It appears to be calling this WalletUpdateSpent function and outputing/adjusting things for each CROC withdrawn -- at line 362. It takes some time to do this -- resulting in the freeze). Maybe lines 362-365 need to be streamlined or made more efficient somehow after more thorough investigation (obviously if line 362 is just a printline only that can be commented out -- but that won't free up too much of the time-lag).

Sorry my C/C++ is really rusty... (I can't remember for-instance what the "::" in the function call is [I think it had something to do with altering the scope of the function-call] and haven't investigated what the BOOST_FOREACH function is doing or where that subroutine/function is declared/spelled-out). it's a medium to long-term-goal for me to get reacquainted with this coding... Tongue

As I'm reading that section of code, it occurred to me this is probably double-spend detection?

This function is also writing to disk, probably many times.

I think the issue could be from the extreme lack of users on the Croc network, since these conditions are happening solely to startsts who has a large hold on it:

if (!wtx.IsSpent(txin.prevout.n) && IsMine(wtx.vout[txin.prevout.n]))

I don't 100% understand what this condition implies.

What is interesting, is it is 1 coin at a time.

I forget which it is - does staking or mining reward 1 coin? I think it is mining. 1 coin per block.

So maybe he is mining so fast he is filling up his wallet / generating a lot of unnecessary traffic?
