There is latency at the start of a call. The log files show that there is a connection timeout when trying to access the followings:
a) https://xx.xx.xx.xx/axis2/services/VPAppLogService
b) VPAppRuntimeVars:getAppVarsAxis2()

This seems to happen when we restart the tomcat instance that serves the OAD application and sometimes without restarting the Tomcat instance.

Questions
1) What does the runtime do at start of a call? And how often does it do it (frequency)?
2) What are 'VPAppLogService' and 'VPAppRuntimeVars:getAppVarsAxis2()' used for?
3) Why are we experiencing this latency?

Always gather a connection to the VPMS for every call.

2) What are 'VPAppLogService' and 'VPAppRuntimeVars:getAppVarsAxis2()' used for?
VPAppLog is responsible for the connection back to the VPMS for logging/reporting and for gathering CAV and global data.

3) Why are we experiencing this latency?
Are you saying it happens once after restart of Tomcat and then is fine without user intervention, or do you need to do something to correct it? Is it fine after the 2nd call?
