Product Issue Awareness
VMware Tanzu Application Services(TAS) and Tanzu Kubernetes Grid Integrated (TKGI)
Slab memory leak has been observed on TAS and TKGi environments utilizing Ubuntu Xenial stemcell versions 621.241 and higher. This issue may result in intermittent unresponsive VM's.
This problem has not been seen on all TAS and TKGi foundations but rather only ones with certain characteristics (BOSH add-ons, specific application workloads).
If the problem began after a stemcell upgrade, then current remediation recommendations is to rollback stemcell (to 621.240 or lower) to earlier version. Check the above article for complete details and recommendations.
