Not sure I understand what you mean by this. Do you mean that syncing is making progress for a few minutes? You see new blocks get imported?

Is the node receiving any RPC traffic? If yes, what kind of calls are you making?

Node receiving many rpc requests (I scan blockchain for my deposits to multiple addresses)

Ok, this could be a bug in the RPC layer. What we need to make progress here is the logs from the RPC request that come in at the time of the panic. Turn on rpc logging with -lrpc=trace. If the machine is receiving a lot of traffic the logs will be VERY verbose so it would make sense to reduce the incoming traffic to the bare minimum before turning on logging.

@androzd Would be useful to know which rpc request was the last before panicking, can you provide that?

For example at 16:39 would be interesting to see the log then.

I can't restore this information.

After 4-5 restarts problem is changed, and now I got a syncing freezes. Syncing delay for 3-5 minutes

Most frequent requests is:
eth_getBalance
eth_blockNumber
eth_getBlockByNumber
eth_getTransactionByHash
eth_getTransactionReceipt

and not frequent is: personal_newAccount.

When freeze starts 100% ram is used (128 GB)

I think we're looking at two separate issues: syncing stalling is likely unrelated to the RPC panic. Let's keep this ticket focused on the panic.
We might need to make some kind of custom build to figure that out. What flavour of Linux are you running?

Also, to get to the bottom of this we'll need to figure out which RPC is causing the panic. @androzd can you please run RPC calls, one at a time and with logging turned on until we find which one is causing this? Thanks.

@baginail Please open a separate ticket if your issue concerns peer count or syncing problems. Let's keep this issue focused on the RPC panic that @androzd is experiencing. Thanks.

Issue with RPC panic is selfsolved.. I don't know how it solved. And I can't reproduce it.

Only issue with syncing now reproduced

Ok, in that case I'm going to close this issue now. Feel free to open a new one if you can reproduce the panic again.
