System information

Geth version: 1.9.12-stable
OS & Version: Linux

Expected behaviour

Node is syncing and accessible and there are no errors like that in logs:
Apr 15 20:28:00 ip-10-10-0-1 geth[15961]: WARN [04-15|20:28:00.398] Served eth_getBlockByNumber conn=127.0.0.1:38060 reqid=1104250 t=10.007163615s err="context canceled"

Actual behaviour

a node can't be reached(Read timed out) and in logs I can see only these lines:
Apr 15 20:28:00 ip-10-10-0-1 geth[15961]: WARN [04-15|20:28:00.398] Served eth_getBlockByNumber conn=127.0.0.1:38060 reqid=1104250 t=10.007163615s err="context canceled"
After a restart, the problem disappears

Steps to reproduce the behaviour

Run geth version 1.9.12-stable with light syncmode

We just fixed a deadlock issue in light client. #20828

Geth v1.9.13 is just released, could you please try it?

Thanks, I've updated to the new version.
If the problem appears again (I hope not), I'll reopen the ticket.
