Prowler Scan Hangs

[jenztales]

Hello,

I'm having an issue running prowler recently. I've updated to the most recent version, and my scan just hangs.

The ulimit is set to 1000

I've checked the permissions for my prowler account in AWS, it's set to 'security auditor.' Any idea what else could be the isue?

I can see prowler accessed the user in AWS today, but the scan doesn't complete. It just keeps spinning and adding time.

Hi @jenztales,

The error jumps in this part of the code:

prowler/prowler/lib/check/check.py

Line 420 in 3d4902b

setrlimit(RLIMIT_NOFILE, (4096, hard))

What’s happening is that your soft ulimit (1000) is lower than 4096, so prowler it’s trying to temporarily increase it, but your OS likely blocks that. This may be caused due to your hard ulimit is also below 4096.

Please check both values, and if I’m right, try to set your hard ulimit to 4096 or higher.
I believe that should fix it.

Okay, let me adjust that and follow up. Thank you, Hugo.

@HugoPBrito Happy Thursday.

I increased the ulimit to 4096 like the code suggests, but the scan is still hanging. I don't have an error message this time, so that definitely did help, but not sure why it's still hanging.

Hi @jenztales, I'm sorry to hear that.

Could you please share more logs? You can use the informational level with --log-level INFO to see where it’s hanging. I suggest trying it a couple of times to see if it stops in the same place. That will give us some more information to have this fixed.

Thanks.
