pm2 monit crashes #5577

Open cameralis opened 1 year ago

cameralis commented 1 year ago

What's going wrong?

I run pm2 monit while a process is running. When specific text is outputted into the log, monit crashes.

How could we reproduce this issue?

I honestly have no idea

Could this be an issue with blessed?

Probably an issue with blessed though. I'll see if I can determine what is causing this.

I submitted a PR to blessed to resolve this issue.
