Managing synchronized reboot of a system

A method comprising:

• in a first management system comprising a primary memory having a used memory and a loosely reserved memory, wherein the loosely reserved memory comprises cache memory having a reclaimable memory:
• monitoring an amount of the used memory and an amount of an available memory during runtime of the first management system, wherein the available memory is an estimate of an amount of memory from the primary memory that is available to start an application;
• determining whether the amount of the used memory is greater than a memory exhaustion first threshold or the amount of the available memory is less than a memory exhaustion second threshold different from the memory exhaustion first threshold, wherein the memory exhaustion first threshold and the memory exhaustion second threshold are determined based on usage of the reclaimable memory and a number of major page faults;
• and
• enabling a synchronized reboot of the first management system in response to determining that the amount of the used memory is greater than the memory exhaustion first threshold or the amount of the available memory is less than the memory exhaustion second threshold.

A non-transitory machine-readable medium storing instructions executable by a processing resource in a first management system comprising a primary memory having a used memory and a loosely reserved memory, wherein the loosely reserved memory comprises cache memory having a reclaimable memory, the instructions comprising:

• instructions to monitor an amount of the used memory and an amount of an available memory during runtime of the first management system, wherein the available memory is an estimate of an amount of memory from the primary memory that is available to start an application;
• instructions to determine whether the amount of the used memory is greater than a memory exhaustion first threshold or the amount of the available memory is less than a memory exhaustion second threshold different from the memory exhaustion first threshold, wherein the memory exhaustion first threshold and the memory exhaustion second threshold are determined based on usage of the reclaimable memory and a number of major page faults;
• and
• instructions to enable a synchronized reboot of the first management system in response to determining that the amount of the used memory is greater than the memory exhaustion first threshold or the amount of the available memory is less than the memory exhaustion second threshold.
