Abstract
Monitoring resource allocation requests to computer resources shared between a plurality of computers includes detecting an allocation request by an application for a first set of the plurality of computer resources and assigning the application to a group, wherein each member of the group comprises a respective application having an associated allocation request for an associated set of the plurality of computer resources. Determining that the first set of the plurality of computer resources cannot be allocated by the application, and determining that the first application generates a function call instructing other members of the group, if any, to request allocation of their associated set of the plurality of computer resources results in incrementing a counter value corresponding to the group. A message is sent when the counter value exceeds a predetermined threshold.
