# BUG: setrlimit(RLIMIT\_CORE) Error

## Description

In Ubuntu 20.04 containers (i.e.: LXC, Docker), issuing a `sudo` command results in the following error: 

```
setrlimit(RLIMIT_CORE): Operation not permitted
```

### Cause: 

Handling of RLIMIT\_CORE appears to be buggy in Linux containers. When sudo tries to restore the original coredump limit (which appears to be RLIM\_INFINITY) as uid 0 it gets EPERM, which should not happen. Sudo 1.8.28 just silently ignored the failure, in 1.8.29 and above a warning is written to the standard error.

## Fix

A fix was implemented in sudo version sudo **1.8.31p1** and above, but a workaround exists if you can not update yet:

```
echo "Set disable_coredump false" >> /etc/sudo.conf
```
