Full network shutdown
My English is not perfect, so for a better understanding of the problem, after the English description I posted the Russian version of this text because most of the developers are Russian
Describe the bug Full network shutdown
To Reproduce
Created a smart contract that sends 10-15 transactions to the addresses of other seventeen(17) smart contracts. 10-15 transactions are sent to each of the 17 smart contracts. A total of 236 transactions and 17 recipients. This smart contract "DSR5wLzZsLJMx5gVAqUAiSBV8CjCbUsjvexdxdbxmqfz"
After I created this smart contract, I sent 1 CS to it, this smart contract sent 236 transactions to the addresses of other 17 smart contracts. Then I sent 1CS to the smart contract which was in the list of these 17 smart contracts. After that, the network began to create 1 block in 1-2 minutes and ignore the transactions that I tried to send in the future. in this mode, the network "worked" for 25 minutes and created 22 blocks in 25 minutes. Then she stopped completely.
Создал смарт контракт который отправляет на адреса других семнадцати смарт контрактов 10-15 транзакций. На каждый из 17 смарт контрактов отправляется 10-15 транзакций. Всего 236 транзакций и 17 получателей. Вот этот смарт контракт "DSR5wLzZsLJMx5gVAqUAiSBV8CjCbUsjvEXdxDbxMQFz"
После того как я создал этот смарт контракт, я отправил на него 1 CS, этот смарт контракт разослал на адреса других семнадцати смарт контрактов 236 транзакций. Затем я отправил 1CS на смарт контракт который был в списке этих 17 смарт контрактов. После чего сеть стала создавать 1 блок за 1-2 минуты и игнорировать транзакции которые я пытался отправить в дальнейшем. в таком режиме сеть "работала" в течении 25 минут и создала за 25 минут 22 блока. После чего она полностью остановилась.
In the same way, stopped the Dapsnet network
Smart contract "7eoo8K8WBUx755kKDunnjVET53X1foYx97hmuDN58PzQ"
Your contract has got a negative balance -> https://monitor.credits.com/testnet-r4_2/Account/DSR5wLzZsLJMx5gVAqUAiSBV8CjCbUsjvEXdxDbxMQFz (#20 bug still exists)
Same on devs & dapps net, negative balance.
Did not see any new blocks in the log or on the monitor, but node kept on working. Judging my logfile I'd say it's either because it's some kind of safety mechanism in the testnet or because a huge amount of (invalid) transactions are stuck in the network.
@ Developers, some community members are still waiting for an installer of the latest testnet version, some have built the node themselves from the available code here on GitHub. It might be possible that there are different contract-executor.jar versions within the network and the consensus protocol causing this.
Starting your node with an old version of the contract-executor.jar shouldn't be possible (which currently is possible I believe), it will not support all functionalities.
Added some log files in case it's needed log_6.zip executor-log-2019-07-19.zip
The negative balance of smart contracts arises militarily, at the moment when it is loaded with “spam” transactions. After all spam transactions are rejected, the balance of the smart contract will return to the correct value. This is a "cosmetic" bug, it is not dangerous judging by my observations
A negative balance should never ever occur, in whatever state it is.

My logfile as uploaded here;
Added some log files in case it's needed log_6.zip executor-log-2019-07-19.zip
contains 813 lines with out of funds. It also mentions they're rejected, but in fact they're stuck, as they're being rejected every time a so called bigbang in the network happens.
@ Developers, starting from line 287963 of my logfile there is a packet of 6928 transactions. In the 7k lines below line 287963 you can see them all being rejected.
