AIT Framework v2 beta4 tips and user feedback
Posted: Thu Jan 20, 2022 3:58 pm
A user reported an issue with AITF v2 beta4 that may cause ancillary data downloads to fail. The problem was indicated by "CRITICAL ERROR: Downloading dynamic data failed" and "TimeLimit expired" messages in output from the `aitf` and `aitf-update-cache` scripts.
The problem was determined to be due to a bug introduced in the AITF v2 beta4 software that results in a 30 second connection timeout erroneously being applied to the ancillary data download itself. Since 30 seconds is likely not enough time for most users to download larger ancillary files, the following workaround is recommended for all users running AITF v2 beta4.
Workaround: Set the CSPP_GEO_AITF_ANCIL_TIMEOUT environment variable as shown below before running the `aitf` or `aitf-update-cache` script. This line can be added to your .bashrc or equivalent.
export CSPP_GEO_AITF_ANCIL_TIMEOUT=7200
This sets the timeout on ancillary data downloads to 7200 seconds (2 hours). Any sufficiently high value can be used.
This issue will be addressed in the next AITF v2 release, at which point the environment setting will no longer be needed.
Please contact csppgeo.issues@ssec.wisc.edu with any questions, or post to this thread.
