500 internal server error accessing large series

[pieper]

Accessing a series using wado-rs series retrieve leads to server error if the series has more than a few items in it.

This URL leads to the crash for instance:

https://proxy-dot-idc-dev.appspot.com/v1beta1/projects/idc-dev-etl/locations/us-central1/datasets/idc_tcia_mvp_wave0/dicomStores/idc_tcia/dicomWeb/studies/1.3.6.1.4.1.14519.5.2.1.2744.7002.150059977302243314164020079415/series/1.3.6.1.4.1.14519.5.2.1.2744.7002.248974378224961074547541151175

It should return a 95MB multipart message of content-type application/dicom. The correct result is provided by accessing the Google dicom store directly.

Probably the proxy is running out of memory or something similar.

Note this is not an issue for OHIF use of the proxy, but does prevent some other uses of the endpoint.

Logs from this time period. Note the 500s are either well after the memory spike, or unrelated. Logs did not capture any errors from what I can see.

Here's a curl command to reproduce the issue:

curl --verbose https://proxy.imaging.datacommons.cancer.gov/v1/projects/canceridc-data/locations/us/datasets/idc/dicomStores/v2/dicomWeb/studies/1.2.826.0.1.3680043.8.498.29634459996408214234588479670784657165/series/1.2.826.0.1.3680043.8.498.39826337616810443783818414516357453289
