09 Feb Solana: With local validator hitting: Transaction simulation failed: Program cache hit max limit
I can help you write an article about the code. However, I have to do more about the project and what you want to achieve. Give more context or find out what you want to do with the Solana program.
Nevertheless, there is a design article here:

Introduction:
Solana is a fast and scalable blockchain platform that uses a clear program cache to optimize events. Like any complex system, however, it can fail under certain circumstances. In this article we examine why a local bravery that hits the cache of the program can lead to the simulation failed: the simulation of transactions has failed and discussed optimal strategies for tree assemblies to prevent such errors.
Why did the event fail?
When a local Valider hits the Solana program, it tries to use the simulation of events in the cache. However, if the cache is filled with the simulations of false or outdated events, the Valider is faced with the error when trying to use the correct simulated space. This can lead to “simulation failed: transaction simulation errors” errors.
Optimal strategies for determining tree **
In order to minimize the risk of this error, it is important to optimize the assembly of the trees for the Sorana programs. Some of the strategies must be taken into account here:
- * Use a balanced wood: balanced wood ensures that the program cache is filled with mixed and false simulations. This helps to reduce the likelihood of an encounter “simulation failed: transaction simulation” errors.
- Use Cache Mechanisms: Create Cache Mechanisms such as reminiscence or cache layer to record simulated events. This can help reduce the frequency with which the validator has to use the program cache.
- Optimize the depth of the wood: Add the wood assembly of the wood. However, note above the performance and ensure that the excess layers are important to achieve the accuracy of the optimal simulation.
- Use a current form of simulation:
Use a current form of simulation, such as:
Example of the wood assembly
Here is an example of the implementation of the configurations of the trees with the created application interface from Solana:
`Rost
Use the Solan_ Process :: {
Account_info :: {Next_Account_info, Accountinfo},
Entrance,
Program_error :: Programrror,
Program_Result :: program result,
Program_error :: Programrrorkkind,
Pubkey :: pubkey,
};
Group! {
FN Main (
_Args: Program_args,
_rogram_id: & pubkey,
_rogram_state: & Accountinfo,
_Initial_state: & [U8],
_next_state: & [U8]
) -> Program result
}
Fn CREATE_TEE_CONFIG (ARGS: Program Args) -> Program Result {
Leave the Tree_Config = Accountinfo :: new ();
// install the wooden configuration using the desired program
Ok (Wood_onfig)
}
`
In this example we create the account information Tree_Config and live with our desired program logic. You can then use this configuration to create a new “program” manifestation.
Diploma:
Although the simulation of event errors in Solan is relatively rare, the understanding of potential causes and the implementation of optimal strategies for tree assemblies can help minimize their effects. If you follow these tips, you can make sure that your Sorana program will be carried out smoothly and efficiently, even in the presence of local validators that make the program.
