Also related, if you have LEGACY_PTYS: |
| 33 |
|
| 34 |
"LEGACY_PTY_COUNT: |
| 35 |
|
| 36 |
The maximum number of legacy PTYs that can be used at any one time. |
| 37 |
The default is 256, and should be more than enough. Embedded |
| 38 |
systems may want to reduce this to save memory. |
| 39 |
|
| 40 |
When not in use, each legacy PTY occupies 12 bytes on 32-bit |
| 41 |
architectures and 24 bytes on 64-bit architectures." |
