## SIGTRAP Browser Crash

If a Chromium based browser inside the workspace session crashes with a SIGTRAP error, it may be an indication that browser
has exhausted the `/dev/shm` shared memory segment allotted to the container. This is more likely to occur if the
browser is running a large number of tabs and/or resource intensive pages.

```

To reduce the likelihood of this error occurring, the administrator can increase the size of `/dev/shm` for the
container by adding a custom value via {ref}`docker-run-config` on an individual Workspace, or at the Group level.

The example below changes the size to `4g` (4 gigabytes). If not defined, the default is `512m` (512 megabytes).

```bash
{
    "shm_size" : "4g"
}
```
