Hello,
I'm having a problem with an odd PHP fatal error which keeps popping up on
open-source Scalr 4.5.1. Here's one way I can reproduce it reliably:
1. click "Add Role" to start the Role Builder
2. fill in the details
3. click "Create role"
4. a message pops up "Cannot proceed with your request. Please try again
later."
5. I reload apache
6. click "Create role"
7. the Role Builder starts building the role
I have a hunch that it has something to do with calling the iterator within
a closure, but I'm not sure. The only way I've found to move past the
error is to reload apache. Here are some installation details and the
stack trace.
- Scalr open-source, version 4.5.1 (ref: a7ab2eda)
- Cloud provider is AWS::EC2, region us-east-1
- Ubuntu 12.04 LTS
- PHP package php5-5.5.8+dfsg-3+sury.org~precise+2 (from the ondrej/php5
PPA)
Apache request:
