Issue/Introduction

cf push / restage / start / restart intermittently fails with the following error message:

json: cannot unmarshal number 18303746057634238464 into Go struct field .mem of type int64

Product Version: Other
OS: Linux

Resolution

The issue occurs due to a potential integer underflow and it is mainly observed in Pivotal Application Service (PAS) / Tanzu Application Service (TAS) releases including garden-runc-release v1.19.18:

• Pivotal Application Service 2.7.30 - 2.7.32
• Pivotal Application Service 2.8.24 - 2.8.26
• VMware Tanzu Application Service for VMs 2.9.18 - 2.9.20
• VMware Tanzu Application Service for VMs 2.10.10 - 2.10.12
• VMware Tanzu Application Service for VMs 2.11.0

While not as common, technically this issue could be observed in older garden-runc-releases prior to v1.19.18.

The fix is included in garden-runc-release v1.19.24. To resolve this issue, you need to upgrade to the following PAS / TAS version or later, including garden-runc-release v1.19.24 or later:

• Pivotal Application Service 2.7.33
• Pivotal Application Service 2.8.27
• VMware Tanzu Application Service for VMs 2.9.21
• VMware Tanzu Application Service for VMs 2.10.13
• VMware Tanzu Application Service for VMs 2.11.1
