Loadmaster WAF Blocking all Client Connections
WAF remote logging would cause the VS (virtual service) to become unresponsive.
Version: 7.2.56 or below
While using our Web Application Firewall (WAF) feature along with WAF remote logging, after a certain amount of time it would cause the system to crash and the virtual service to become unresponsive.
|Steps to Reproduce:||
|Error Message:||wafd: XX: Hit connection limit 64000|
|Cause:||When a VS is configured with WAF enabled, there are two processes which are related to WAF, one for managing the traffic and performing the WAF capabilities (wafd) and one for handling the logging and passing that logging off to remote logging endpoints. (mlogc). The pipe between wafd and mlogc would become saturated and cause failures.|
|Resolution:||Resolved in firmware version 7.2.57|
