Hi everyone! I have two questions related to user function probes: Firstly, I am trying to have a process attach more than 1024 uprobes, however, I am getting the error: "failed to create BPF link for perf_event FD 1023: -24 (Too many open files)" even after changing ulimit -n to 4096 github issue[1]. Secondly, I am running some tests with uprobe and uprobe_ret in multiple functions in the redis binary, but I am noticing that when counting the times the uprobes and uprobes_ret are called, in the end they do not match 1 to 1. Either individually (a uprobe/uprobe_ret in the same function), or the total sum. Is this a predictable behaviour? I am tracing several functions in such as [2].
