A lot of transactions stuck in local node pool

Geth node does not release the transactions to pool. Transactions are stuck. When I realized this problem I saw there weas a new version. I updated Geth from 1.9.12 to 1.9.17 but the problem was not solved.

After the update, while using 0xdac17f958d2ee523a2206206994597c13d831ec7 contract and run eth_estimateGas method I get "invalid opcode: opcode 0xfe is not defined" error.
