Suggested Answer: A 🗳️
Cause -
This issue is occurs if the allocated JVM maximum memory heap is too low for the VMware Inventory service, VMware Profile-Driven Storage service, or VMware
VirtualCenter Web Management service.
Several core vCenter Server services use individual configuration files (wrapper.conf) to determine the JVM maximum heap size that each service can use. The
VMware Inventory service, VMware Profile-Driven Storage service, and VMware VirtualCenter Web Management service rely on the JVM maximum memory heap configured in their individual wrapper.conf file and play a critical role in the functionality of vCenter Server.
: If vCenter Server 5.5 has recently been updated beyond 5.5 U2, see
Upgrading VMware vCenter Server 5.5 to 5.5 U2 or later reduces the JVM maximum

Note -
memory heap size (2114669)
.

This is a known issue affecting vCenter Server 5.x.
To resolve this issue, manually set the inventory size.
To change the JVM maximum memory heap size for a Windows installed vCenter Server 5.x, see, see
Configuring Tomcat server settings in VMware vCenter
