After running Parca@https://github.com/parca-dev/parca/commit/ffa83684b5ea40cb3c30d672542e8d100e15f5ad for some minutes, this error message started showing up many times: ```level=error name=parca ts=2022-07-14T14:28:04.535566133Z caller=logger.go:35 protocol=grpc grpc.component=server grpc.service=parca.profilestore.v1alpha1.ProfileStoreService grpc.method=WriteRaw grpc.method_type=unary grpc.start_time=2022-07-14T15:28:04+01:00 grpc.code=Internal grpc.error="rpc error: code = Internal...
Lately, we've been debugging some issues that were rooted in race conditions (https://github.com/parca-dev/parca-agent/pull/444, https://github.com/parca-dev/parca/pull/1136). After several hours of running, we no longer store broken debug files, but I wanted to...

Something we have experienced in libbpfgo is that it's not hard to accidentally double-free resources (see this bug we recently hit https://github.com/parca-dev/parca-agent/pull/367 that ASAN catches https://github.com/parca-dev/parca-agent/pull/370), which beyond crashes, could...
👋 . Been using libbpfgo recently and found some problems with the way errors are being handled. Would love to hear your opinion and comments on this subject 😄 ....
To use https://github.com/aquasecurity/libbpfgo/issues/195 instead, as we need the active CPUs
After we land https://github.com/parca-dev/parca-agent/pull/627, there will be some outstanding work: - [x] https://github.com/parca-dev/parca-agent/issues/631 (Fixed by https://github.com/parca-dev/parca-agent/pull/641) - [x] https://github.com/parca-dev/parca-agent/issues/635 (Fixed by https://github.com/parca-dev/parca-agent/pull/641) - [x] Run the new setup in minikube...
`_start` is ELF binaries' entry point which eventually calls `main`, we fail to symbolise it with the following error in Parca: > ```level=debug name=parca ts=2022-07-12T20:53:00.094324562Z caller=dwarf.go:57 component=symbolizer file=tmp/fcef7244132f0fec86f3e2007c25809032b990b9/debuginfo buildid=fcef7244132f0fec86f3e2007c25809032b990b9 liner=dwarf...
As we use some C library wrappers and Golang can't prove the lifetime of objects at compile-time, it's possible that `parca-agent` is not memory safe. It's very important that we...
