Work flow execution in Buildmaster takes lot of time

We have been using Buildmaster 3.6.5.6 which suddenly starting working slow, when we execute a particular workflow, it just hang for a longer time and get executed after almost an hour..
So we tried upgrading it to the latest version of 4.0.6 and still the issue persists.

Hi Ketan,

There's not much information for us to go on here... can you isolate where the slow down is occurring (Specific action, server initialization, etc)?

Hey Tod, Its when we execute the workflow, it hungs after the execution is started. the very first step after it starts, still I kept the work flow going on.. and it took 208mins to execute all the steps which generally shall take not more than 2mins...

A simple app pool recycle on the target system takes more than 30mins.

I verified the communication with the target system and the agent .. they are working fine... the ports and communication between both the servers is good did the telnet and its responding... I can transfer the data between both the servers using normal copy within seconds... so no network issues.

I can see the agents as ready for the target system.
