Received about 40 failed monitors all with a similar error message:
23 Apr 2014 01:12:05 AM, "Computer: DatabaseServer [99.99.99.99]", "Monitor Title: Ping 99.99.99.99", "Description: 99.99.99.99 is not responding to ping requests within 3000 ms. Received no response from 99.99.99.99 Error due to lack of resources. [Err=0x2B02 (11010), CurrUser=MonitoringAcct, Imp={none}]"
Same cycle of errors repeated about 4 hours later. We've not seen "Error due to lack of resources" since deploying the product more than a year ago.
The server is single-function, dedicated to PA Monitor. Although VMware is in use, there is no thin provisioning. We observe CPU spikes at about 28%, memory usage is flat at 1.2gb. Disk is 55%/98% free on the system/non-system volumes.
Looking for cause of "lack of resources" with this error code.
