问题
I am using an bpmn process which is already running using thread and also using spring ftp where the Task scheduler thread is running but I found the application is cannot switch from the threads. Is there any way to invoke the task-scheduler process without any interrupt and I am using InboundchannelAdapter to copy files from FTP. Please suggest any feasible way to resolve the issue.

I don't see any issues in your question. And to be honest it fully isn't clear.
Please, be more specific and sharing some code/config/logs/stack-trace sometime is really useful. More info, more chance to get quick and proper answer.
I guess your problem that you download files from FTP and in the same thread run a BPM process which might block eventually waiting for some actor action.
Fro this purpose you should shift Spring Integration flow on the <poller> to different thread and don't steal task-scheduler resources. They are really so expensive for the whole system. Consider to use enough big ThreadPoolTaskExecutor for the task-executor reference on the <poller>. Also there is an ExecutorChannel for you with similar thread shifting capabilities.
